Hello again,
Just a small clarification:

Right.

The routine is actually not used for exception support per se, but only for
the computation of call-chain backtraces.
It turns out that it is most often used together with exceptions, to attach
to exception occurrences a traceback describing the call-chain at the point
of the raise.
This is optional, however, and missing this feature does not prevent the base
exception support to work.
