I think raymond's post more correctly described it. Rather than do
things right, it is more the "world view of python", just that it has
been pushed too far in certain situation(mostly unconciously) and
turning it into a holy war. We seem to see it every where, not just
about a programming language though.

Exactly, it is the functionality, not syntax that matters.
"if-then-else" vs "then-if-else", does it really matter other than
proving one is "righter" ?

I kind of understand the rationale behind it now, thanks to another
post. I think the argument is that Python is intended for people
without prior programming experience and that the current behaviour is
more "intuitive"(people expect 321321 in the example case), how that
conclusion is drawn I have no idea but could be valid.

The real life situation though is, Python is usually not the first
language one learns and the net result is that one has to unlearn/wash
away what is learnt to appreciate the pythonic way. But that since we
never has a chance of this "from pure to python", we would never
appreciate that as we already know things about mutable/immutable
object. Thereful, we would not make the mistake of expecting "321321"
and thus no chance to appreciate the "oops, what is this not a iterable
error, let me lookup the manual" saga.
