How would a PEP to remove this feature fare today?

I'd very much prefer that we kept them. I find it a useful way to group the behaviour of the looping - this bit is the normal loop, and this bit at the end is when the loop fails/is exhausted. This is obviously for when you use it in a loop where you're looking for a certain result. And yes, you can do something similar with try/except, but I find that ugly - 'break' is the natural way to get out of a loop, not 'raise'. I find using exceptions in this way to be a sort of horrible goto-hack, and makes the code hard on the brain.

(obdisclaimer: for/else gets a mention in my OSCON python tutorial, so I'd appreciate it if you don't rip it out in the next month )
