I find pragma once more convenient and does not add more symbols to the intellisense.
I think we need to write a code convention document, things are getting messy and we need to agree on alot of stuff. I want our code to look clean and professional like the C++ codes I see here in Microsoft.
It is ok if we over time apply our agreed coding conv on each file we touch. Will be better than go mass change the engine and make alot of conflicts.
