   Possibly fixed by b6cb6bb.

   I'm now seeing "TypeError: 'gcc.WrapperMeta' object is not iterable" with Python 3.8 and GCC 10. My current hunch is that it's an issue with Python 3.8's typeobject change (tp_vectorcall_offset), but that's a hunch right now.

   The error "TypeError: 'gcc.WrapperMeta' object is not iterable" is caused by generate-gimple-c.py with the tp_flag Py_TPFLAGS_DEFAULT in series of generated classes pytype = PyGccWrapperTypeObject(identifier = 'PyGcc%s_TypeObj' . When changes it to Py_TPFLAGS_BASETYPE . The error will disappear, although this will lead to a crash.
   The reason is clear, in py38 some logic changed in PyType_Ready function.

   My solution was to strip out the entire metaclass #192
   It seems there is another patch possible #188
