Martin,
The question wasn't "which is better?". The question was "are the two
functionally the same?" which as you've pointed out, they're not.
Steffen,
Looking at the (longer) code example that you posted, I can see that in
both cases there is logic to stop the iteration if there is a problem.
So, in this case, you may be correct.
I think the larger point that Yoav and Remmy were both trying to make is
that evaluating a newcomer's re-factored code is as time consuming as
refactoring it themselves. If it means getting a bug fixed or a MAJOR
performance gain, then it's worth it but to risk overlooking something
subtle and breaking a core component for a small gain in efficiency or
just to neaten the code is not worth the risk.
