Class::MOP::MiniTrait - Extremely limited trait application
|
|

|
=head1 VERSION
|
|
|
|
version 2.2014
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This package provides a single function, C<apply>, which does a half-assed job
|
|
of applying a trait to a class. It exists solely for use inside Class::MOP and
|
|
L<Moose> core classes.
