I would think that how localized the effect of the goto is would be far more important than whether it goes forward or back. Jumping back to the beginning of a function from the middle might be good. Jumping somewhere else, probably not so much.

Agreed, that wouldn't be too terrible, but then, again, I think that I always end up using a while loop for those cases when I have to "redo" stuff.
