It's weird how many different perspectives there are on what's
basic Haskell.

Someone asks about mapM, and everyone agrees about that - it's
definitely on the short list of things we want to know - but then
we go on to liftM, which I've always thought was kind of a gratuitous
extra way to spell >>=.

We get to IO, and of course everyone agrees that it's on the short
list (even if we differ on when to get to it), but -- IORef?  Can't
tell if you're serious.
