It is not faster program execution wise.
Typing a few letters does not make a difference to me, even if I handfill a 4x4 matrix.
But if you play lazy ass you will learn that the compiler does not replace that with a more performance friendly construct (ie my handwritten one) and that you will lose a fair amount of performance.
No problem for a single instance array, there I wouldn't use the handwrite approach
But for vectors and the like (speed critical), this approach is plain wrong and defeats the purpose of optimized math routines.
