Some Haskell programmers use fmap (because most Monads are also Functors), others use liftM. Both have the same effect: given a monadic computation "m a", "liftM f" turns "f" into a function that operates on the enclosed "a" instead of the entire "m a".
That is, given the theory behind it all, every monad is a functor (note the lower case); from
