Oh sure, Irakli is just making do with what happens to work. SpiderMonkey doesn't do source recovery, so it needs something special and the label hack Irakli found is "it" (for now!).
This thread was about standardizing something guaranteed that does not depend on toString, but we would love to have a winning library approach whose API we can standardize. Such a library could be scrappy (I hope not crappy ;-) about using "what happens to work" on particular engines and even versions.

That's the other thing about a library approach: it doesn't need to land in language, but then the IDE may have to grow a full parser (probably good IDEs already have one).
