[Changes for 0.21 - 2007-01-26]

* Helper functions for mapping keys are no longer present within
  dynamic scope of mapping construction callbacks; this allows you
  to have call a method that has the same name as a mapping key
  during ->new() and other callbacks.

* Support for fully qualified fields: "Very::Happy is 42" and
  "is Very::Happy" are valid even when Very::Happy is not yet loaded.

* Support for associating coderefs with copula for even more
  flexible rewriting of arguments:

    copula      => {                # list of words, or a map
        is  => '',                  #  from copula to label prefixes,
        are => '',                  #  or to callback that e.g. turns
        has => sub { has => @_ },   #  "has X" to "has is X" and
                                    #  "X has 1" to "has is [X => 1]"
    },

* Sub::Override is no longer a dependency for this module.

* Values in declarations can now contain nested sub-objects by
  calling the declarators again:

    column foo => field is column( field is 'foo' );

[Changes for 0.13 - 2006-07-21]

* Introduce the "synonyms" interface, a mapping for alternate
  spelling for field names.

[Changes for 0.12 - 2006-07-20]

* The "isn't" keyword in 0.11 broke Test::More, and I can't find a
  way to reconcile them, so it's now sadly retracted.

[Changes for 0.11 - 2006-07-20]

* Support the prefix ! operator on declarations, so negated ones
  such as "!is global" or "!global is $x" now work.
  Requested by: Jesse Vincent

* Also introduce the "isn't" negated copula.
  Requested by: Jesse Vincent

[Changes for 0.10 - 2006-07-20]

* The "copula" interface now accepts an arbitrary prefix for each
  copula (defaults to ''), which can be used to distinguish labels
  built by different copular words.

[Changes for 0.09 - 2006-07-18]

* The "mapping" interface now accepts arbitrary code reference as the
  builder function, in addition to class names to call ->new to.

[Changes for 0.08 - 2006-07-18]

* Added lots of documentation and comments.

* Now works correctly even if at runtime the symbol table entries
  created at compile-time get deleted.

[Changes for 0.07 - 2006-07-18]

* Chained "is foo, is bar, is baz" now works; previously only
  the first one is recognized.

[Changes for 0.06 - 2006-07-17]

* Documentation cleanup; no functional changes.

[Changes for 0.05 - 2006-07-17]

* Support for ordered declarations, via list-context return of 
  "declare".  In scalar context, it still returns a hash reference.

[Changes for 0.04 - 2006-07-17]

* Support for plural values via "are":

    column x =>
        field1 is 'xxx',
        field2 are 'XXX', 'XXX', # <-- Plural value
        is field3;

[Changes for 0.03 - 2006-07-17]

* The declarator can now be exported to another package;
  this works because internally, each declarator remembers
  the class mappings and copula it was associated with.

[Changes for 0.02 - 2006-07-17]

* Documentation cleanup; no functional changes.

[Changes for 0.01 - 2006-07-17]

* Initial CPAN release.
