[Python-Dev] decorate-sort-undecorate

[Christopher A. Craig]

If this goes in can we document that adding a key parameter makes the
sort stable and key=None causes a stable sort to happen?  Current
CPython won't have to do anything at all with that, but other Pythons
(or a future CPython where a mythical faster-than-timsort nonstable
sort is discovered) would have a documented way to force stability.
