Thank you very much, Antoine, for your review. My comments in reply:
- the dead code: it's not dead, IIRC it ensures that at least one argument is given, otherwise it raises an exception.
- PyUnicode_GET_SIZE: you're right. The previous patch didn't have this problem, because there were two loops: the first one made sure in advance that all arguments are PyUnicode.
- the false comment: right again. A remain from the first patch.
- dotted_getattr and references: right! I should have noted better what Raymond's initial loop did.
Attached a corrected version of the patch according to Antoine's comments.
