Hi Nick,
Yep, PEP 315. Sorry about that.
Now, about your suggestion
do:
while

This is pythonic, but not logical. The 'do' will execute at least once, so
the else clause is not needed, nor is the . The should go before the while terminat
Ok, I see your point. Really, I've read more about Python than worked with
it, so I'm out of my league here.
Can I combine your suggestion with mine and come up with the following:
do:

I'm against infinite loops -something religious :), which explains the call
for the do loop.
The issue about the parser is over my head, but the thought had occurred to
me. Now, it would not affect while loops inside do loops, wouldn't it?
Cheers,
Hans.

Hm, doesn´t seem to be so for my regular python.

Thanks! That seems to have cleared things up -- the section names are
now node2.html, node3.html, ..., which is what I'd expect

+1 from me. Should you mark PEP 315 as rejected?

It's because you are using Windows. The way -0.0 gets rendered
depends on the platform. As Tim points out, try
math.atan2(0.0, -0.0) vs math.atan2(0.0, 0
