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

[Martin Teichmann]

New submission from Martin Teichmann:

When a new class is initialized with __init__ in a metaclass,
the __class__ cell of the class about to be initialized is not
set yet, meaning that super() does not work.

This is a known but fixable problem. The attached patch moves
the initialization of __class__ from the end of __build_class__
into type.__new__. This avoids the proliferation of methods
which don't have the __class__ cell set.
