Perhaps we could allow reraising whenever the existing traceback chain contains a reference to a frame that is an ancestor of (or equal to) the newly raising frame?

This is starting to sound terribly hairy.

Would it help if a different syntax were used for raising and reraising? Raising would complain if there were already a traceback, and reraising would expect an existing traceback and extend it.
