[issue12370] Use of super overwrites use of __class__ in class namespace

[Nick Coghlan]

As the checkin message says, this is once again a problem on trunk. The relevant test is still in place in test_super.py, I just marked it as an expected failure.

unittest.mock is currently avoiding the problem via the "_safe_super = super" workaround.

So, we need a new patch which fixes the misbehaviour *without* breaking the new tests I just added. I'm thinking something which special cases __class__ references in a ClassBlock to be dual purpose (i.e. both locals *and* closure variables) may be necessary, rather than the current approach of always coercing them to be closure variables.

resolution: fixed ->
