Hello,
I've never used monads but I have a problem that feels like it could
be solved elegantly with them.
I have a sequence of functions of arbitary size and an input sequence
s. Each function is given a sequence and returns a sequence that can
be bigger than the input sequence. I want the

If any of the functions return nil, I'd like the computation to stop.
I don't see any real reason not to use
(reduce #(if %1 (mapcat %2 %1))

overflows, though. Just keep that in mind (or add a tactically placed doall).
Sincerely
