I am wondering if this kind of optimization it's really needed.
Donald Knuth said a long time ago that the difference between
micro-optimizations and premature
optimizations is that the first ones are driven by measurement while the second
ones are driven by guesses, intuitions and hunches.
@Chris - you guess or you have measured it?
