I think the diverged from talking about the "var" keyword in particular towards duplication in general a long time ago. However, I still think that DRY is empirically proven. > Where is your proof?

It is true that I did not provide this proof because Colin O'Dell did claim this fact in the very initial message of this thread and I believe him. > There is no reason to remove it from ANY version of PHP.

I did not say that we should change for change's sake. I only stated that trying hard to prevent change by all means is wrong. Again, this diverged away from the "var" keyword alone a long time ago and was more a general statement. TL;DR Thanks for yet another aggressive/provocative email, I stick to my +1. However, you all have valid points to keep it. -- Richard "Fleshgrinder" Fussenegger
