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

I know I was too lazy to clean it up :-P ( I also blame Dons for 'go' )

I think the Common Lisp community tends to use 'foo-aux' instead of 'go' for these sort of axillary functions. But, then in Haskell we can't use hyphen as an identify character and underscore is not popular. For this reason I started using fooAux in Haskell, but after learning that a single quote is valid identifier character I started using foo'.

Other than using go and foo', what do people use in Haskell?

You could combine Lisp and Haskell and say foo'aux :-) Cheers Ben
