Is there really no question? I question the assertion, for one. Just because a language allows a bad habit doesn't mean it's a feature. Leaving your handles open can lead to unpredictable results, which is somewhat anathema to the idea of correct programs, unless broken features are part of your

If you open a file for writing and then exit with output unflushed, then Haskell does not flush the file for you. In ghci the program seems to work, but then when you compile it in ghc it mysteriously fails. I've just been bitten by this, but when I went to the bug tracker I found http://hack
