82 While L<Moose> attributes provide you with a way to name your accessors,
83 readers, writers, clearers and predicates, this library provides commonly
84 used attribute helper methods for more specific types of data.
86 As seen in the L</SYNOPSIS>, you specify the extension via the
87 C<metaclass> parameter. Available meta classes are:
93 This points to a hashref that uses C<provider> for the keys and
94 C<method> for the values. The method will be added to
95 the object itself and do what you want.
99 This points to a hashref that uses C<provider> for the keys and
100 has two choices for the value:
102 You can supply C<< {method => [ @args ]} >> for the values. The method will be
103 added to the object itself (always using C<@args> as the beginning arguments).
105 Another approach to curry a method provider is to supply a coderef instead of an
106 arrayref. The code ref takes C<$self>, C<$body>, and any additional arguments
107 passed to the final method.
113 times_with_day => sub {
114 my ($self, $body, $datetime) = @_;
115 $body->($self, sub { $_->ymd eq $datetime->ymd });
122 $obj->times_with_day(DateTime->now); # takes datetime argument, checks day

157 This is an early release of this module. Right now it is in great need
158 of documentation and tests in the test suite. However, we have used this
159 module to great success at C<$work> where it has been tested very thoroughly
160 and deployed into a major production site.
162 I plan on getting better docs and tests in the next few releases, but until
163 then please refer to the few tests we do have and feel free email and/or
164 message me on irc.perl.org if you have any questions.
168 We need tests and docs badly.
172 All complex software has bugs lurking in it, and this module is no
173 exception. If you find a bug please either email me, or add the bug
