Comment (by nbruin):
Replying to [comment:48 rws]:
> Secondly, to ask interactively for a missing assumption a message has to
be given in the terminal different from the error message tied to the
original `RuntimeError`. So, simply re-raising is not an option if you do
not like `RuntimeError: ECL says: Maxima asks: Is _SAGE_VAR_a an
integer?`.
In that case we know exactly what happened and the original traceback
doesn't have to be kept. Raising a a fresh exception with a fresh
traceback should be fine. It's when you find that the `RuntimeError`
you've just caught is *not* the one you expected that the original
traceback is valuable. And in that case you probably don't want to mess
with the exception object itself either, so a bare `raise` should do the
trick. The scenario of changing the error object but keeping the original
traceback should be quite rare.
> So, in my opinion, unless someone comes up with a better solution, this
ticket will have to wait until Sage is Py-3.
which may be a very long time. It nice to do things in a Py2/Py3
compatible way if possible (which can be done here, I think), but if not
we'll just have to fix it if/when sage transitions from Py2 to Py3.
