[Haskell-cafe] A small display problem using Helium

Hello, I've written something simple: main :: IO () main = do lijn <- getLine putStrLn lijn Now if I import it in Helium it will do the following: Test> main test -- (here I'm typing test) test it will be displayed two times, why? Because it displays my input and the output of the function. Now I want to write a function that does NOT display my input, any suggestions how I can achieve this? Thanks in advance!
