Thanks for this. I'm relieved to know I'm not thinking the "wrong" way. :) But, honestly, I could not articulate the problem as you have. I wish I had your knowledge. The idea of a "jump" really captures it. setjmp. goto. It's navigating memory. And nothing more. I can visualize the problem, sort of - I just intuitively feel like sets, Lisp-like lists, and vector-based approaches, are the way to go in high level programming - but I do not know the right words to describe and argue my point. As such, I doubt I could convince many high level programmers to abandon the use of iterations in the code they write. Again, you have beautifully articulated what I could not. Cheers.
