Wow! That was enormously helpful. Thanks! One further question: I have the lexer/parser in optimized mode, in order to increase the startup speed of the program. Is there any way, past neutering the ply source code, to stop it from writing tables if not run in optimized mode? IFAIK, the disabled checks in ply give me much more of a speedup than just hte -O mode. The problem is that when it tries to write the tables, it can't open the files in "w" mode (they're installed in /usr) and so it crashes. Right now, I have the code neutered - if it fails to write the tables, it just silently swallows the exception. This isn't the best solution. Is there a better one?
