And ultimately, future optimizers will hopefully make twice as good 
vectorized code from scalar source than any human can produce anyway. 
Optimizing plain C code (for CPU) was once a rewarding art, but nowadays 
it's often just a Bad Idea because it just confuses the optimizer and 
stops it from producing much better code than you could think of anyway.
