I don't think there's a single good answer here.

Creator-knows-best sounds more attractive to me.
At least it handles name collisions between classes better.
If Modules A and B each define a class MyClass and an
instance of A.MyClass reaches Module B, should it suddenly
acquire the behavior of B.MyClass? What if the instance variables
are different?
