Hi,
In Python 3, exceptions don't behave as sequences of their arguments;
they only provide a tuple (i.e. the object you can deconstruct) as
"args". Would this be acceptable?
(enum, estr) = e.args
Adding custom behavior to exceptions is possible by subclassing
PyExc_Exception instead of using the PyErr_NewException helper. So you
could say both `(enum, estr) = e` and `e.enum, e.estr`. The
disadvantages are that iterable exception is non-standard in Python 3,
and that subclassing in C involves a lot of boilerplate.
