Are you familiar with the concept of Turing Equivalence? Once a

not you can get things to happen, it's about how much pain you ut the

And the above behavior essentially breaks the main utility of
behavioral inheritance: that you can cause more-specific behaviors to
occur in a more-general context. Really, this is just wrong.

So it's a bug that you know how to fix?
