Sorry to spam you Jeff, again I sent my email to the poster rather than the
list. I'm using Yahoo beta webmail and don't see a way to set it to reply to
the list rather than the originator. Anyway, this was my post:
Hence the need to perform a "run" operation like runIdentity, evalState or
runParser (for Parsec) to get something useful to happen. Except for lists we
don't seem to do this. I suppose lists are so simple that the operators :, ++
and the [] constructor do all we ever need with them. Finally there is no
runIO because "main" is essentially that function in every real program? - Greg

One general intuition about monads is that they represent
computations rather than simple (already computed) values:
