Re: [Haskell-cafe] Trying to write 'safeFromInteger'

That seems a really weird way to write it! Who decided all auxiliary functions should be called go? (I think I'm blaming dons) - why not: sffi :: (Integral a,Num a) => Integer -> Maybe a sffi n | toInteger n2 == n = Just n2 | otherwise = Nothing where n2 = fromInteger n No need for auxiliary function definitions. Thanks Neil
