Stupid wuestion about Monads :)

[Hal Daume III]

Look through the mailing list archives/wiki/haskell tutorials.  But
basically you can't, except by combining it with another action, as in:

suppose 'baz :: Int -> IO Bool', then:

foo = do
  bar <- baz 5
  if bar
    then ...
    else ...

for instance...
