In the message I sent before the one above, I gave what seemed to me the cleanest way to do what you originally asked, using pre-increment as I suggested in my first reply:

Yes, I did see that and I tried it out; pre-increment gives problems just the same as post-increment. So that wasn't a solution.

Thanks for the update. [...]

Using "((i++)) || true" allows me to say, I don't care if the arithmetic result is zero, I am handling the condition for loop exit outside of that result and the actual return from the ((i++)) is totally irrelevant.

Thanks for the feedback, I'm glad you found that useful.
