Good point.  It also makes the better point that trying to use key= when you 
really want cmp= would be pretty awkward.  And examples like Andrew Dalke's 
file comparator (that compares file size before comparing content) would be 
more awkward to write this way.  (If nothing else, he'd have to use your 
wrapper function.)

I'm convinced. ;)
