# need to be compatible with Moose::Meta::Method, which isn't possible. the
# right solution here is to make ::Meta into a role that gets applied to
# whatever the method_metaclass happens to be and get rid of
# _meta_method_metaclass entirely, but that's not going to happen until
# we ditch cmop and get roles into the bootstrapping, so. i'm not
# maintaining the previous behavior of turning them into instances of the
# new method_metaclass because that's equally broken, and at least this way
# any issues will at least be detectable and potentially fixable. -doy
