Even in Haskell this separation isn't absolute. Programmer errors, such as dividing by 0, can and do lead to exceptional conditions. The proper way to handle dividing by 0 is to not do it in the first place, but if it happens because of a programming error, you've got an exception. Unfortunately this encourages programmers to think that handling the exception is the proper way to deal with this condition, but it isn't.
So I have another question. Is the following function safe and legitimate?
safeDiv :: (Exception e, Integral a) => a -> a -> Either e a safeDiv x y = unsafePerformIO . try . evaluate $ div x y
I believe it should be okay to use this 'safeDiv'. What do you think? -- c/* __o/* <\ * (__ */\ <
