(1)  The __this_*__ PEP was written and posted; I'll revise it slightly tonight.

One benefit would be a minimal-change version of super.

(2)  Calvin's and Tim's more complete reworking of super.

(3)  final/once/name annotations -- I *think* this was dropped when
case statements were rejected, but I'm not sure.

Does the alternative need to cover 100% of use cases?

If it covers 99%, should the other 1% become impossible, or should we
keep __del__ as fallback?
