I sometimes think it was a mistake to introduce elif just to save typing "else if". The problem with the elwhile/elfor/eltry idea > is that you're just as likely to need e.g. a "try" in the else clause of a while-loop as another while, Here's an idea for Python 3000 which addresses both of these: Split 'elif' back up into 'else if', but also generalise it so that any 'else' can be followed by any suite-introducing statement. Then you get all possible combinations for free.

I don't think that's a good idea. What would the following monstrosity mean?:

if 0: print "Ran the if" else for item in (1, 2, 3): print item else try: print "No exception here!" except: pass else: print "Who's else is this, anyway?"

The use-case of 'elif' or 'else if' to avoid nested if statements is strong, but the use cases for the ability to mix compound statements together is significantly weaker.

Cheers, Nick.
