        "When I first read 'Warnock applies' on things in p6 summaries a 
        year or so ago, I thought it was some really energetic programmer 
        who went around and applied patches as soon as people posed 
        a question."

        subject: Nested statement modifiers
        summary: Paul Seamons asked why multiple nested statement modifiers (`say "foo" if $foo for 1 .. 3`) are disallowed. A long discussion on the technical and ergonomical problems was stirred up. The general consensus is that there is still no good reason to allow nested statement modifiers.

        summary: |-
          In a subthread of '<msgid:200609011052.00562.parrot@seamons.com>',
          Aaron Sherman asked what the semantics of exceptions within hyper
          operators are. Larry explained that since hyperoperators imply not
          caring about the order of the side effects (for multithreaded
          goodness), which element generates an exception might be
          implementation dependent.

        subject: class interface of roles
        summary: |-
          Last week,
          TSa wondered how [typing of
          mixins](http://www.jot.fm/issues/issue_2004_11/column1) would
          look in Perl 6.  A code example of how it might look was included.
          There were also some questions on roles in Perl 6.
          
          This week, Sam Vilain thought that it would be the same as requiring
          that a class implement a method, except for a difference in syntax.
          This led Brad Bowman to ask how a role can require a target class
          to implement a method or do another role.  Stevan Little answered 
          that he believed this was done by providing a method stub.  Jonathan
          Lang mostly agreed with Stevan and offered more details.
          
          chromatic thought that forbidding methods was potentially like
          the false-cognate problem.  Stevan admitted that he had yet to
          find a real-world use for it.
          
          There was further discussion on roles.

        subject: Motivation for /<alpha>+/ set Array not Match?
        summary: |-
          Last week, an earlier discussion on S05 subrules continued.  Audrey
          Tang wondered if there was a hidden cost to making `/<foo>+/` always 
          react so that `$<foo>.from` returns something.  Carl Mäsak
          preferred the proposed semantics and asked if 
          the question had been discussed off-list.
          
          This week, Audrey replied that there had been no further discussion.
          Carl asked for a short snipped to illustrate it, and supplied an anecdote
          about [Warnock](http://en.wikipedia.org/wiki/Warnock%27s_Dilemma) applying.

        subject: 'RFC: multi assertions/prototypes: a step toward programming by contract'
        summary: |-
          Last week there was a great deal of discussion on this subject.
          
          This week, Tsa asked, in response to Larry Wall's comment, 
          if namespaces give a structural type definition.
          
          Also, Aaron Sherman started a new topic entitled 'Abstract roles,
          classes and objects'.  He asked rhetorically what was the use of
          an interface which doesn't give a guarantee.  Trey Harris responded
          that there are three ways to manage a guarantee: an 'is abstract' marker,
          some type of inference, or by disallowing abstract classes.  Jonathan
          Lang offered his definition of 'instance management'.

        summary: |-
          Joshua Choi asked how coercion interfaces are implemented and implicitly used.
          Musings on roles and the terror of implicit coercions in C++ were part of the discussion, but surprisingly the `as` multi method was not mentioned at all.

        subject: "\"Don't tell me what I can't do!\""
        summary: |-
          Jonathan Lang initiated a long discussion by objecting to programming
          styles where a programmer can intentionally prevent someone else from
          taking what is otherwise a legitimate action.  He cited an example from
          the recent discussion on allowing a role to prevent the consumption of
          another role ('<msgid:45101204.30301@barco.com>').
          
          There was a suggestion that restrictions could be purely advisory.
          This led to the question of whether strict is localized.  Larry
          Wall replied that the default is for lexically scoped pragmas, but
          that S01 states that it must be possible to write policy meta models.
          More discussion on this topic followed.

          Aaron Sherman posted that he was considering creating an archive
          of messages from the mailing list which would be easier to search
          than Google.  The problem with the Google archive is that it includes
          discussion, and he's only interested in decision.  He asked for 
          opinions on the examples he posted.  Darren Duncan suggested seeding
          from the existing mailing list archives.

        summary: |-
          Markus Laire quoted a section of S04 on lines ending with
          `}` followed by nothing but whitespace or comments.
          He wondered if this meant that an else statement like
          `};`
          `else {`
          would be the same as without the semicolon.

        summary: |-
          Jonathan Lang wanted to know what would happen if
          he imported two modules which export the same method.
          He felt that the resolution should be similar to role
          composition techniques.  He suggested some syntax.
          Aaron Sherman thought that only plain multis would
          conflict, and suggested a warning would be most
          appropriate.

        subject: requirements gathering on mini transformation language
        summary: |-
          Last week,
          Allison Randal asked for a volunteer to write up the requirements
          for a mini transformation language to use the compiler tools.
          The job would involve spending time with Allison and Patrick
          Michaud and combining their ideas along with your own perspective.
          Adriano Ferreira offered some opinions on the subject, and
          Markus Triska volunteered to do it if it relates to his area of
          expertise.
          
          This week, Aaron Sherman expressed confusion over the purpose of
          this project.  He thought TGE performed this task.  chromatic replied
          that the mini language would be "the stuff in curly braces" in the 
          TGE grammar files.
          
          Adriano Ferreira named some desired features in a transformation
          language, such as a data structure pattern language, and rules which
          are selected via the patterns.
          
          Allison reported that there were several volunteers.

          Last week, Jonathan Worthington committed a draft PDD on Parrot's
          bytecode format.  Ben Morrow wanted to know if pbc files could allow an 
          optional `#!` line so that they could be used as executables.  Jonathan 
          replied that he had considered this, but rejected it because it is 
          UNIX-specific.  There was additional discussion on the topic.
          
          This week, Karl Forner suggested working around the need to specify
          the absolute path by using the `env` command.

        subject: 'Heads up:  Dynamic environment now captured in continuations'
        summary: |-
          Bob Rogers announced that as of r14830, continuations capture the
          dynamic environment in order to restore it properly on invocation.
          He also noted that moving the `control_stack` slot broke coroutines,
          but that he suspected this was due to problems with coroutines.  He
          asked to know if any problems with coroutines developed.  François Perrad
          replied that he'd been unable to implement coroutines in Lua.
          Bob Rogers was not surprised, and discussed some of the problems involved.

        subject: Emacs/vim code coda placement
        summary: |-
          Paul Cochrane reported that the Perl::Critic policy for the coda
          skips `__END__` and `__DATA__` sections, but vim requires the coda
          to be within the first or the last 5 lines of the file. 
          Chris Dolan agreed with Paul that using `=cut` for POD in the
          `__END__` section would work, but was not sure how to handle `__DATA__`.
          Will Coleda approved putting the coda after the `__END__`.

          Karl Forner wrote that he has been working on FixedBooleanArray and
          ResizeableBooleanArray.  Ticket <rt://perl/40066> indicated they
          needed to be rewritten.  He also looked at bug <rt://perl/39063>
          on ResizeableBooleanArray using 64 bytes per bit.  He thought that
          it would be best to rewrite the PMC.  He had a few questions on
          what was desired in an implementation.  Bernhard Schmalhofer and
          Leopold Toetsch tried to answer the questions.
          
          From this, Karl concluded that the best solution might be to use
          an external lib.  He also described two other possible approaches.
