in thread Peek a hash without breaking iterator

Actually he IS changing the user's code to effect debugging. As I understand it he is effectively inserting a command to copy the hash into the code he is debugging. So in fact a custom implementation of each is still one way to stop the real one breaking.

One world, one people

    How? Code is running, enter inside loop, hash copy resets iterator. Too late for simulation. You mean add simulator before loop, through magic, before its needed because its ok to reset iterator at that point? How many frames back is safe? Too much overhead?
