I've always called my local definitions of this function `sortOn`. I also
frequently define `groupOn`.
I dislike the suggestion to use rewrite rules. It's not always an
optimization to memoize the key to sort on. For example, `sortOn id` is
probably slower than `sortBy (comparing id)`. Also, if the key is very
large, it could be a pretty bad regression.

a bit generic, without giving that much of a hint, perhaps something
like 'sortMapped' could be a bit more telling. Greetings,
Daniel
