Ideally, the system would provide such information on
its own, but that is not yet a feature.

Parse transforms may be what you want. I have written
and used a parse transform (smart_exceptions) that
provides line information and a bit more for most
exceptions. In the same framework, you can also write
your own custom exception handlers. 

I will prepare it for "external use" and check it into
jungerl in a couple of days.

Best,
Thomas
