Note the flags: METH_CLASS says that it's a class method and
METH_COEXIST says that it should use this method instead of the slot.
"(PyCFunction)" is redundant, Py_GenericAlias already has the right
type. Overuse of casting to PyCFunction can hide actual bugs.
I borrowed that from listobject.c, which does have the cast.
METH_COEXIST is not needed. There is no slot for __class_getitem__, and
even if it was, there would be no reasons to prohibit using it.
