You are technically right.

But that "when" approach took me like a charm...
I have argued that "then" and "when" just make
a difference of a single letter. This was completely
crappy, since "when" replaces "if", not "then".

Isn't that just elegant? Elegance is a very
high level of Pythoniciy, rarely reached.
I really, really like it.

I now realize that I wasn't so unhappy with the order
of constructs, but of the misplaced "if", literally.
"when" is much less of a problem to me.

Think it over - ly y'rs -- chris
