I'm not quite sure, but I'd guess either one of
1.) It does not compile at all because of suspicious indentation
2.) It will just print "A" but not "done" because that is considered beeing
in the else-branch.

Dear Cafe -
Sometimes, a comment can change the meaning of a program. No? Well, but "commenting out" a line of code certainly does. So, can you guess what this program will output?
main = do if True then do putStrLn "A" else do -- putStrLn "B" putStrLn "done"
I nominate this for inclusion in a hypothetical Haskell equivalent of http://www.javapuzzlers.com/
