Thats why i put those quotation marks around that part of sequence ;-))
AFAIK one-liners never were about comprehensibility, just about what you can cram into one line of code.

Any programmer should have no problems guessing what the line does does (even more so when looking at the "final" version without the abundant liftM's), the beauty of it lies in figuring how the heck it does what it does. And figuring that out should bring the "profound enlightenment experience; that experience which should make you a better programmer for the rest of your days, even if you never actually use Lisp -erm Haskell- itself a lot" (my apologies, P. Graham, for cannibalizing your words).

I should probably get myself a signature stating that i will explicitly warn the reader when being serious ;-)
