Hi
My intuition is only best and fastest code goes to library, to the point that people can learn from it. It seems I was mislead.
The compilers change over time - meaning that the fastest code may change over time. There is also the chance that the original code was not the best - for example the words function in the standard library performs two additional isSpace tests per word. The original code specifies an interface, its thanks to people trying to beat the performance that things improve. Thanks Neil
