But don't monkeypatch current_metaclass. I'll know if you do.
This meta_lookup feature has not yet landed on Moose master (much less a released version) but it has gotten preliminary approval of the rest of the dev team. :) This copy/paste of Moose::Role's code was one of the most distasteful parts of MooseX::Role::Parameterized. I'm excited that it now leverages the version of Moose::Role you currently have instead of the 0.60 era code I copied. Better error messages, future-proof for new keywords, etc.
