Well that probably depends on a whole lot of things that aren't evident from the examples or your description.

Why not:
return grep { $_->can('new') } $self->domain_classes;
Also, it's somewhat silly to use the word "class" for something that's not a class. (An abstract class is not a class.) When you think "abstract class" and you are a Perl programmer, you really want roles.
