[issue23722] During metaclass.__init__, super() of the constructed class does not work

[Nick Coghlan]

Nick Coghlan added the comment:

Martin, the patch isn't currently applying to trunk - would you have time to take a look at that?

Ned, this is tangentially related to Martin's work on subclass initialization in PEP 487: one of the current problems with zero-argument super is that we don't actually populate the class cell until quite late in the type creation process, so even after the metaclass.__new__ call finishes, zero-argument super still doesn't work yet.

That aspect of the change is clearly a bug fix, but fixing it will have the side-effect of making "__cell__" visible in the class body during execution as a CPython implementation detail.

Would that still be OK to go into beta 2 rather than beta 1?

(Assigned to Ned due to the release management question)
