PEP 315: Enhanced While Loop

I was just doing this yesterday:

print "Type 'exit' to quit..."
line = raw_input("> ")
while line != "exit":
     process_line(line)
     line = raw_input("> ")

With the new PEP it would look like this, I think:

print "Type 'exit' to quit..."
do:
     line = raw_input("> ")
while line != "exit":
     process_line(line)

Of course, I only had one line of setup code so the PEP didn't actually 
shorten it a lot, but I can imagine what this would do to bigger examples.

I rather like it.
