Um... Does anybody else find it interesting that we are "showing the 
beauty of Haskell" by attempting to construct the most terse, cryptic, 
unmaintainable tangle of point-free code that the combined mindpower of 
the entire mailing list can produce?

Yes, there is much to be said for the power and brevity of Haskell. But 
you *can* go over the top here, people! o_O

Keep it short _yet comprehensible_, IMHO.
