NAME
    selfvars - Provide $self and @args variables for OO programs

SYNOPSIS
        package MyModule;
        use selfvars;

        # Write constructor as usual.
        sub new {
            return bless({}, shift);
        }

        # Use $self in place of $_[0].
        sub foo {
            $self->{foo};
        }

        # Use @args in place of @_[1..$#_].
        sub set {
            my ($foo, $bar) = @args;
            $self->{foo} = $foo;
            $self->{bar} = $bar;
        }

DESCRIPTION
    This moudles adds $self and @args keywords to your Perl OO module.

    They are really just handy helpers to get rid of:

        my $self = shift;

    Behind the scenes, $self is simply tied to $_[0], and @args to
    @_[1..$#_].

    Note that they are variables, not barewords.

INTERFACE
    $self
        Return the current object.

    @args
        Return the argument list.

DEPENDENCIES
    None.
