It's ambivalent in my opinion. It works with Python 3. But I think the
case here is that nobody has run the PyLint over GDB Python API script
usage to check for these scenarios.

Yes, in the source tree see gdb/python/py-function.c. I've not had a
chance to check it yet or if, in fact, there is something we could
tweak. It's never come up before ;)
