Typically caused by IO going wrong in some way, like the machine running out of swap and your program terminating, a file not existing, etc. Many newbies get syntax errors because they sometimes put it there. In a Haskell file, you're only allowed to write bindings using =.. What you could do is put the following in the Haskell file: myHandle = do h <- IO.openFile "testtext" IO.ReadMode return h In addition to remembering indent, I saw this sentence at the website I first started Haskell: Note that there are no = right after the function name and its parameters, before the first guard. @Greg Haskell doesn't recognize tab character '\t'. Exception. Instance details. This is important too. The above will parse a string like "aabbb" and return a successful parse result "aabbb".
