This utility module is designed to help authors of Moose extensions
write extensions that are able to cooperate with other Moose
extensions. To do this, you must write your extensions as roles, which
-can then be dynamically applyied to the caller's metaclasses.
+can then be dynamically applied to the caller's metaclasses.
This module makes sure to preserve any existing superclasses and roles
already set for the meta objects, which means that any number of
=item * method_metaclass_roles => \@roles
+=item * wrapped_method_metaclass_roles => \@roles
+
=item * instance_metaclass_roles => \@roles
=item * constructor_class_roles => \@roles
This function will apply the specified roles to the object's base class.
-=head1 PROBLEMS WITH METACLASS ROLES AND SUBCLASS
-
-Because of the way this module works, there is an ordering problem
-which occurs in certain situations. This sequence of events causes an
-error:
-
-=over 4
-
-=item 1.
-
-There is a class (ClassA) which uses some extension(s) that apply
-roles to the metaclass.
-
-=item 2.
-
-You have another class (ClassB) which wants to subclass ClassA and
-apply some more extensions.
-
-=back
-
-Normally, the call to C<extends> will happen at run time, I<after> the
-additional extensions are applied. This causes an error when we try to
-make the metaclass for ClassB compatible with the metaclass for
-ClassA.
-
-We hope to be able to fix this in the future.
-
-For now the workaround is for ClassB to make sure it extends ClassA
-I<before> it loads extensions:
-
- package ClassB;
-
- use Moose;
-
- BEGIN { extends 'ClassA' }
-
- use MooseX::SomeExtension;
