However, if "__tostring" has been defined, no traceback is added.
Are you willing to share the reasoning behind this with us?

The idea is that the object would be an 'error object', who's __tostring() might be a detailed stack trace.

This means that you can forge useful tracebacks from otherwise weird code (e.g. a stack of callbacks).

Throwing random objects as errors doesn't make a lot of sense in the first place.
