What I'd really like to see is a lexer that parses operators by rules rather than lists. If '+' is a token and '++' is a single token, then '+++' and '++++++++++' should also be recognized as tokens (which aren't used by the language). The only actual effect would be to would turn currently legal expressions like 'a+++++b' (and '5....a') into syntax errors. -- Rainer Deyke - rain...@eldwood.com
