[gameprogrammer] Re: std::string alternative

Like I originally said, every function call is slower. I don't have the URL (maybe someone can find it) but if you read the Halo 2 postmortem they got a 5% speed increase by turning off exceptions.

So does extra work at the compiler level still translate into slower performance in code execution? Or does it just take a little longer to compile (with exceptions turned "off") but runs as fast as possible. I personally wouldn't mind adding a little bit of compile time, but I'd hate to impact my overall game performance...

anyway then there's zero difference in functionality.
The compiler does extra work before going in to any function if it knows (via declarations) that it has to handle some exceptions being thrown, in order to 
properly handle the way exceptions are passed back up the call stack.
