I meant to dig through some real code, but forgot because I was writing code for work. This example on my tablet is the general pattern I often need though. And obviously I've solved it one way or another hundreds of times.

This is why concrete examples are much easier to discuss, heh.
In any case, it's often possible to either (a) redefine the inner loop
as some sort of container operation, or (b) redefine the outer
operation as a function, and use "return". So it would be helpful to
have an example that CAN'T be rewritten in one of those ways, to use
as a compelling example.
