Simulating C-style for loops in python

Question

(even the title of this is going to cause flames, I realize)

Python made the deliberate design choice to have the for loop use explicit iterables, with

Answer 1

This is the best I can come up with:

def cfor(first,test,update):
    while test(first):
        yield first
        first = update(first)

def example(blah):
    print "do some stuff"
    for i in cfor(0,lambda i:i

I wish python had a syntax for closured expressions.

Edit: Also, note that you only have to define cfor once (as opposed to your complicated_iterator function).
