Perhaps I read a little to much into this:
The idea that new code is better than old is patently absurd. Old code has been used. It has been tested. Lots of bugs have been found, and they've been fixed. There's nothing wrong with it. It doesn't acquire bugs just by sitting around on your hard drive.
I interpret this as, "Age of the code is irrelevant. But if the application blows up on unexpected input and after careful review found to have been designed wrong there can be justification for a rewrite."
If I'm totally way off base and this is a "GOTO is never good" article, I completely recant what I posted earlier and deem this article useless for its too hard-nosed approach about programming decisions. TMBOOWTDI - There Must Be Only One Way To Do It? No thanks. I'd rather be allowed to bend the rules when I can justify them adequately.
