Need help with code generation
...unity we strive to very high software quality standards. Even if we don’t meet our own standards having them changes the community emphasis. I think having those standards is a huge part of why the LLVM codebase is as high quality as it is. I hope that a commitment to general software quality is a cornerstone of LLD. Not treating all segfaults as P0 bugs is not a decision based in software quality. -Chris > because I think there is a real difference between a project which can be easily exploited, and one that takes effort to exploit. > > > Would it end this thread if I went that way?

MVC and modules. Views telling models to behave
I was thinking today, it would be nice if a view could tell a model how to format it''s data for that particular view. Kind of like, the view is bestowing instant, and temporary knowledge on the model for the duration of the views run. It seemed to me that this would be more objecty than say a helper that formats a string format_my_string( my_string ) Instead, in my view. Lets assume I
