71 While L<Moose> attributes provide you with a way to name your accessors,
72 readers, writers, clearers and predicates, this library provides commonly
73 used attribute helper methods for more specific types of data.
75 As seen in the L</SYNOPSIS>, you specify the extension via the
76 C<metaclass> parameter. Available meta classes are:
82 This points to a hashref that uses C<provider> for the keys and
83 C<method> for the values. The method will be added to
84 the object itself and do what you want.
88 This points to a hashref that uses C<provider> for the keys and
89 has two choices for the value:
91 You can supply C<< {method => [ @args ]} >> for the values. The method will be
92 added to the object itself (always using C<@args> as the beginning arguments).
94 Another approach to curry a method provider is to supply a coderef instead of an
95 arrayref. The code ref takes C<$self>, C<$body>, and any additional arguments
96 passed to the final method.
102 times_with_day => sub {
103 my ($self, $body, $datetime) = @_;
104 $body->($self, sub { $_->ymd eq $datetime->ymd });
111 $obj->times_with_day(DateTime->now); # takes datetime argument, checks day

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