On the other hand, they may come at a performance cost and have very
little use.
Comparison are open-coded by the compiler, so this will require a compiler
change but won't cause any performance penalty.
As for mapcar, it is pretty slow already, and the main cost is in
calling the user's function. That won't get any slower.
