As usual, that only works part of the time. [1,4,15,3,7] is not a computation, it's a list of numbers. A plain and simple everyday value.
But isn't a value of (IO String) equally plain and simple?
Sure, but saying a value of type IO String is "a computation (in the IO monad) returning a String" makes more sense to me than saying [True,False,True] is "a computation (in the [] monad) returning a Bool".
For sure, and in general when people speak of monads they're really talking about IO, true? If that's disappointing, maybe it would help to have a word for it, maybe `IO String' is an "irreduceable monadic value" or something. Donn
