That seems to be a reasonable assertion, but it seems to be at odds with Forth's being about as fast as GNU C on Pentiums and PowerPCs when doing the same task. Almost anything related to programming intrests me, and probably others, but I think we've gone into a bit too much detail in dragging the thread off topic.
