This is a good reason for having named attributes instead
of a tuple -- it's extensible without requiring these sorts
of hacks.

As for the C function problem -- are these functions
instantiating some known exception class? If so, why
can't that class be given an __init__ that accepts the
appropriate arguments positionally and stores them as
attributes (or passes them on as keywords args as per
my earlier suggestion)?
