I suppose Python could go all the way and say things like
Traceback (innermost last):
foo.py:25: in Spam.eggs
but that might be more intimidating for a beginner.
Besides, you Emacs guys have plenty of programmability anyway :)
You would have to do a little parsing to get the file name and
line number from the current format; it's no more work to get
it from the suggested format.
(What i would really like, by the way, is to see the values of
the function arguments on the stack -- but that's a lot of work
to do in C, so implementing this with the help of repr.repr
will probably be the first thing i do with sys.displaytb.)
