Control.Monad has a function (called "sequence") that does this for you. In
fact, "sequence" is a more generic solution since its signature is
(Monad<http://haskell.org/ghc/docs/latest/html/libraries/base/Control-Monad.html#t%3AMonad>m
=> [m a] -> m [a]).

As a newbie, I found it educational to peruse the various modules in "
http://haskell.org/ghc/docs/latest/html/libraries/". Just start looking at
modules that sound interesting and see what has already been defined. Some
modules at first may be too advanced, but if you go back to them in a few
days (weeks?), they'll start making more sense, too.
