-=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 (C<ClassA>) which uses some extension(s) that apply
-roles to the metaclass.
-
-=item 2.
-
-You have another class (C<ClassB>) which wants to subclass C<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 C<ClassB> compatible with the metaclass for
-C<ClassA>.
-
-We hope to be able to fix this in the future.
-
-For now the workaround is for C<ClassB> to make sure it extends C<ClassA>
-I<before> it loads extensions:
-
-  package ClassB;
-
-  use Moose;
-
-  BEGIN { extends 'ClassA' }
-
-  use MooseX::SomeExtension;
