We might allow the creation of traceback objects, but without any custom frame objects it is unclear how useful that would be.
When I was implementing Pyrex, I would have found it very useful to be able to create Traceback objects without Frames, but only if the Traceback were able to hold a line number.
As it was, I had to create an entire fake Frame object filled with mostly dummy values, just to get line numbers printed in the traceback.
