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.
