Thanks again for sharing the big picture: you have before, but I see you've evolved it slightly. Delayed error handling I've had occasion to do, but not yet in Python. The constrained jump pattern is interesting, but the example is not complex enough to justify the syntax: the with solution is actually longer... if you initialized result they'd be the same length. The problem with the for/else construct is that the "not found" case falls through to the "found" case, which can be awkward, but that awkwardness isn't really demonstrated in the example. "exitlabel" is an awkward name, too, since there are no labels, and no exit(). (yes, I know you meant exit the loop; naming is hard.)

You exit with statements - that's why the final method is called exit.

Cheers, Nick.
