You could try smart_exceptions in jungerl (or github if you're feeling brave, where I'm working on a rewrite). It tries to mark all exceptions with module, line, etc. I have found it quite helpful, but it's not a bulletproof drop-in replacement.

Ideally, the compiler should of course do this instead.
