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.
