> Can't this be fixed in the CONTEXT_CHECK_VA macro? No, the macro should only allow contexts. E.g. in the case of localcontext(None) context_copy(local, NULL) would be called on local=Py_None, which is undefined. What would perhaps be needed for a nice C-API is a function like PyArg_ParseTupleSkipNone() that treats None arguments in the same way as optional args that are not given.

No, the macro should only allow contexts. E.g. in the case of localcontext(None)
context_copy(local, NULL) would be called on local=Py_None, which is undefined.

What would perhaps be needed for a nice C-API is a function like

   PyArg_ParseTupleSkipNone()

that treats None arguments in the same way as optional args that are
not given.
