No, but I have used Objective-C quite a bit, and it, too, discourages exception-driven control flow. Still, it has @try/@catch for those situations where it's unavoidable. > Maybe golang-style panics would be best given their own parallel system, rather than touching the semantics of $@, no matter how slightly. > > In short, I'm opposed to try/catch, as I think it's a tired idiom with superior alternatives, including what Perl's already got. I think it's fine to have a parallel system, but Perl *already* has exception-driven control flow, and whether or not you or brian d foy prefers a different approach, I think the existing system should be improved.
