* I think we have talked about this before, when reviewing D lexers. I'm thinking of how to handle invalid data. Is it the best solution to throw an exception? Would it be possible to return an error token and have the client decide what to do about?
Hmm... my initial reaction was "not as default - it should throw on error, otherwise noone will check for errors". But if it's returning an error token, maybe it would be sufficient if that token throws when its value is accessed?
