To make these two special names work, I replaced the standard traceback
formatter with a formatter that looks for these names.  However, the
special formatter also replaced filenames with module names, which
annoyed other developers, so they ripped out the special formatter.  I
think it would be beneficial to bring back the special formatter, but
this time output filenames instead of module names.

See zope.exceptions.exceptionformatter.
