Yes there are. Google Closure compiler does export this thing called Source Maps (http://www.html5rocks.com/en/tutorials/developertools/source...) which is very exciting.

If it weren't for the fact that we don't get column numbers in window.error, I would have already supported source maps in http://errorception.com/ by now. I'm still looking actively for ways to include support though.
