Are you saying that it would be OK to peek inside the function at
compile-time and capture self.__class__ then, rather than waiting for
run-time (when self might really be a subclass instance)?

On its own that seems reasonable, but the "peek early" proposals are
starting to add up, and they aren't all consistent.

   The stuff inside a function definition doesn't get evaluated until
the function is called.

    Except that if it has "yield", that changes the compiler settings.
 Nothing gets evalated, we just peek.

    And a switch creation does get evaluated early (if that happens).

    And a static/once/final variable gets evaluated early (to line up
with switch)

    And a super gets created early, but only halfway.  It freezes
self.__class__, but not the self.__mro__
