I think the reason that ASSOC-IF, RASSOC-IF and friends do not have :KEY
arguments is that ASSOC-IF is equivalent to FIND-IF :KEY #'CAR and
RASSOC-IF is FIND-IF :KEY #'CDR. That is, the way I think of these
functions, they already have a KEY argument, it is just that the KEY is
already implicitly specified by the function name.
I don't see any substantial advantage of expressiveness in this
proposal.
