rewriting cmp_to_key in C is underway

Nice to know! Any chance this wil get into 2.7.x?
Python 2.7 still have list.sort(cmp=...)/sorted(cmp=...), so cmp_to_key
is not much use there. Just pass your comparison function to the cmp
argument.
.cmp_to_key was added to ease moving to 3.x or maintaining code usable
on both. A faster version would encourage such use. But it is not a bug
fix exactly, and there is always worry that permanance enhancements may
have unforseen side effects. I will let Raymond make the call on this.
