(do/once constructs nested up to three deep)

That's not something to be proud of, you know. It means that you've failed to decompose your logic into smaller fragments.

Actually it means he's probably trying to do multiple things which need unwinding, but because he can't use three goto labels and rely on fallthrough he has to add a layer of almost-entirely-redundant nesting for each one.

This is not something that you'd call out as an advantage and a sign of great experience unless you didn't actually have much. (But it's been worth reading this thread anyway: it's not every day you see people telling Al Viro that he doesn't have enough experience to judge the relative worth of exception-handling goto versus other techniques!)
