Comment:

 I'm going to close this ticket, as the immediate issue of `maximumBy` and
 `minimumBy` using too much stack space with lists has been fixed with
 2e43848236a4b80015d8fb09a87f6f6a746c1365.

 There's still the other issue of ways to improve the current situation
 even better that ekmett discusses in comment:26, but I believe that is
 best left to a separate ticket.
