I'm not the OP, but this can of course be implemented by having an
additional (hidden) field in the exception which contains the source

I'm not sure how expensive this would be. But it would be useful to have,
at least as a compiler option. I suppose raising of an exception is
expected to be slow anyway, as opposed to installing an exception
