main :: IO Int main = return 1
This does different things when compiled and when run with runghc/runhaskell (it prints an extra 1 with the latter).
For practical purposes, I think it is beneficial if either of the two ways to run a Haskell program have the same output.
Or did somebody intend this to happen?
