Also, were the lexer dependent upon the parser you couldn't store the
tokens in an archive nor could you use a totally different lexer
(e.g. a handwritten one, output from another lexer generator).
It's sometimes hard to draw the line between the two, especially for
"weird" languages, where you sometimes feel the urge to somehow
direct the lexer from the parser, unfortunately. But keeping them
separate is a Good Thing(tm), IMHO.
