Hi, seeing Haskell 2010 and http://hackage.haskell.org/trac/haskell-prime/wiki/DoAndIfThenElse saying: Compiler support ¶ GHC full (no flag) I wonder why I still get a "parse error (possibly incorrect indentation)" for: \begin{code} main = do if True then putStrLn "1" else putStrLn "2" \end{code} Can I try out this feature somehow? Cheers Christian
