In any case, this will have to be judged on benchmark numbers, once Mark (or someone else) massages the interpreter to experiment with those runtime memory footprint reductions.
This I absolutely agree with. Without evidence we're just waving our prejudices and varied experiences at one another (for example, my experience that the "modern processors" you were talking about have massive caches, so memory access isn't as much of an issue as you might think vs your experience that memory access matters more than doing a shift-and-mask all the time). I've seen no hard evidence of any actual improvement of any size, and without that there really isn't a decision to be made.
