People can code C or C++ without an understanding of the code the compiler will generate from the source they give it... it is my contention (for this particular example) that their code will run slower than code written by someone who understands what the computer is going to end up doing with the code. I think it might be time to license people to code... "coding without a license... that's a $500 fine..." 8-).
