Rasmus Wriedt Larsen e2652591a5 Python: Change perf fix PoorMansFunctionResolution
Thanks @yoff, this leaves us with the following evaluation, which looks
very close to the one in the other fix (but with cleaner implementation)
-- both at 688k max tuples (although numbers are not exactly the same).

```
