Ah, it's failing in the last line that I showed in the snippet above (calling `PySequence_Size`), but we fail to check for a python error afterwards (I suppose because the code assumed that would always work because of the sequence check before that). Checking for a python error and raising this one, correctly gives the "TypeError: object of type 'A' has no len()" error. Looking at the python C API docs, it indeed mentions that `PySequence_Check` always passes for objects with `__getitem__`: https://docs.python.org/3/c-api/sequence.html#c.PySequence_Check -- This is an automated message from the Apache Git Service.
