[docs] [issue18334] type(name, bases, dict) does not call metaclass' __prepare__ attribute

[Nikolaus Rath]

Nikolaus Rath added the comment:

In that cases, maybe type(name, cls, clsdict) should actually raise an error if there's a metaclass with __prepare__ involved?

Presumably that would break only code that was already broken, but it would convert previously hidden behavioral bugs into an explicit expressions raised at the right point.
