Thank you for your answer (that should go also in Issue 4705 ). If you are
right, then:
- I want both functions for "min with key" and "max with key" (putting only one
of them in Phobos sucks);
- I prefer an unary function instead of a binary function. When you get used to
unary functions they are much more handy.

So I guess you can call call them keyMax and keyMin.
