Currently writing a compiler that I want to be production strength, so I read your article. Thank you! It's interesting that your specifically call out that putting source lines in is not good when most modern compilers seem to be moving the other direction and putting them in. Do you think it could be a preference thing? Would it be good to have the option for the user to turn it on? Also, thanks for the tip on the spell checker. That is something I'll add. You said they your just used the current symbol table as a dictionary in another comment; that is a great idea too.
