I am not sure it makes any sense to apply a trait to a required method for a couple of reasons
-
A number of traits will interact with the body, so the lack of a body would require that those traits handle this case and that seems like an extra burden for not much reward.
-
Since traits are not inherited (by design) then really this basically is just wasting resources to do something that will do nothing.
You could suggest that traits should just no-op (not call the trait function) on required methods and just mark the trait as having been applied, but this too has the problem of completely breaking any trait which might want to use side effects, again creating a special case.
Additionally inflating required methods to be full mop::method objects would be wasteful of memory.
As for the bug in unapply_all_roles please make that a separate issue.
