Yep, it should mostly work in general - but it's not something that anyone really tests (as far as I know) and it's likely that upstream language developers wouldn't want to spend time fixing any bugs that we might find. Also, I don't particularly want to have to spend a bunch of time chasing down these kind of bugs (see http://www.mikeash.com/pyblog/friday-qa-2013-06-28-anatomy-of-a-compiler-bug.html for and example of the kind of thing that we might end up having to deal with). -- Daniel J.
