What's wrong with the status quo? Our current lexical rules *seem* complicated to newbies, but just like everything else in Haskell it carries a deep simplicity; having only one rule (maximal-munch) gives a certain elegance that the proposals all lack.
I'm quite in favour of "maximal munch", but after munching "Foo." or "Foo.where" saying:
Sorry I've munched too much, I meant to munch only "Foo" and "." (because Foo is a data constructor) or "Foo.wher" and "e" (because "where" is a keyword)
carries "simplicity", to "deep" for me.
Apologies, if the above sounded rude. In fact, I just realized that the tokenizer can decide what to do with "Foo." or "Foo.wher" when seeing the next character. However, it is not helpful at all, when the lexer passes "Foo.wher" and "e" to the type checker. The programmers's input deserves more respect. C.
