Re: gnubol: The token "IS"

["Boris Kortiak" <BKortiak@genlyte.com>]

Would this not be an excellent example of a pre-lexer?  With it you could check to make sure that all uses of IS/ARE, SPACE/SPACES, ZERO/ZEROES, &c are correct.  Correct if possible (e.g. "IS IS" becomes "IS") and flag as a warning and lex out, otherwise flag as an error and lex out the whole statement before passing on to the next step.

Of course I could be way off base (not unusual).
