Agreed, though I think ';' is the wrong punctuation for this... It's always
been a statement-seperator, and now it's used to seperate parts of a
statement, like a normal comma. I still think 'for x in a; y in b' is better
than this, but I'm not sure how to liase it with list comprehensions'
"nested for". But then, I'm not sure about any of the list comp syntax right
now :-) To paraphrase Guido, I got myself in quite a mess ;-)
Anyone object if I pull this discussion into c.l.py ? I'm not sure if any
new ideas pop up, but it might give some more data to work with ;-P And I
don't think any of this is urgent in any way, I doubt anything more will get
done until after ORA OSCON, anyway. And maybe some of you guys that are
actually going there can discuss it face to face ;-P
