Hi
Reading through the code to lex, it appear that it will return [("","")] if and only if all isSpace t.
If this is really the case, does it make sense to state all isSpace t? It has a much clearer meaning to me.
I think 'lex' is supposed to not understand (haskell-style) comments - which I agree with - so I agree that it would be "better" to say (all isSpace t). I might even have thought that in passing when reading that code, I don't remember....
My particular reason for wanting this is that read :: Int -> String depends on lex, when logically reading an Int doesn't appear to warrant lexing Haskell! Thanks Neil
