Not sure -- I think I carefully designed the old format to be one of the formats that Emacs parses *by default*: File "...", line ...

Yes, this is much easier in Python. Watch out for values that are uncomfortably big or recursive or that cause additional exceptions on displaying. --Guido van Rossum (home page: http://www.python.org/~guido/)
