MooseX::AttributeHelpers::MethodProvider::Array

=head1 DESCRIPTION
This is a role which provides the method generators for
=item B<unshift>
+=item B<clear>
+
+=item B<delete>
+
+=item B<insert>
+
+=item B<splice>
+
+=item B<sort_in_place>
+
+Sorts the array I<in place>, modifying the value of the attribute.
+
+You can provide an optional subroutine reference to sort with (as you
+can with the core C<sort> function). However, instead of using C<$a>
+and C<$b>, you will need to use C<$_[0]> and C<$_[1]> instead.
+
+=item B<accessor>
+
+If passed one argument, returns the value of the requested element.
+If passed two arguments, sets the value of the requested element.
