You've hit the nail on the head. One of the big ideas of the "structured
programming" revolution of the '60s–'70s was *functional decomposition*:
the idea that if your program is doing more than one "thing," you should
break it down into smaller functions where each function accomplishes just
one "thing." Every time you find yourself needing "the equivalent of
`return` but for a smaller part of a *foo*," structured
programming's answer is always going to be: *Break that foo down into
smaller functions, and then use `return`.*

`return` is the `return` you're looking for. :)
