As I mentioned to Christian in a private email, I have a system which is 350K LOC. Now not all of that gets loaded at one time of course (thank God for __autoload()!), but there are times when a significant proportion of it is loaded. And then it munches memory. Yes, I can strip the comments from production code. But that defeats the object of the getDocComments() reflection code. And screws me for my fallback attributes methodology :-( ... ... ... > I'm not too thrilled about this deal.
