[Haskell-cafe] lex

Hi, does anybody know, why 'lex' isn't faithful to the Haskell-syntax? Since it isn't difficult to make it ignore comments, handle qualified names and recognize octal/hexadecimal literals (the system, be it hugs or ghc, does it, and I filled in the required code this evening, so for a good programmer it would be a matter of half an hour at most), I suppose there must be a reason, only I can't think of one. If you have any good ideas or even know the reason, please tell me. Thanks in advance, Daniel
