You do realize that, at least on a PC, it's just as fast accessing an array on 
the stack than one that was dynamically allocated, right? Actually, if you're 
accessing more than one int at the time, the dynamically-allocated one might 
be faster because of better memory alignment.

And if you're talking about the extra indirection added by 
boost::scoped_array... I admit I haven't measured, but I doubt very, very 
much you would notice any difference unless all your program did was run in a 
for loop accessing array elements.

Personally, I see nothing wrong with simple defines for things like that. It's 
when you start doing complicated macros that the pre-processor can become 
more of a problem than it solves.
