That's just a bit more off-the-wall than adding for keywords (the three
above, plus I've been corrected on the while thing). Let's not get too
hyperbolic here; it doesn't help the discussion along much.

If you want if/else if, talk to Larry (I would not disagree, though old
friends are hard to part with). I'm just saying that as long as if has
the syntax it has, we should replicate that on loops.

We've had a lot of good thought here, and I see this as anything but a
mindless squabble.

See the thread that Damian started, which discusses these options.

Correct, and this has been pointed out previously in the thread. Thank
you for collecting it.
I think the reasoning for each, respectively is:
1. Consistent syntax with if/elsif/else
2. Cleaner
3. No new syntax required
I agree with all three points. I have a feeling we're not going to get
if/else if, but if we do I prefer the second. If we don't I prefer the
first.
