If failure is not frequent, I usually use an exception. The other
methods mostly depend on style, I guess.

One solution not given in your list is CPS: call a continuation
procedure in case of success (with some arguments) or return
#f on failure.
(Incidentally, this will likely to be the fastest solution on Chicken
which uses CPS internally anyway)
