This is of course undecidable to verify statically, so we can't just crawl
PyPI... however, I would argue that using mixed float-int lists is
dangerous, and is more dangerous in Python 3 than in Python 2. So hopefully
this is not very common. However, even if 10% (surely a vast overestimate)
of sort calls are to mixed int-float lists, my patch would still yield a
significant savings on average.

It hasn't been mentioned in this thread :)
