Just to clarify, I am suggesting to have the unchanged messages in
tracebacks, but having some methods in the exception to get the exception
and message localised. Just like repr() and str() are directed at different
audiences (the programmer vs. The user), so is a traceback vs a message box.

In English, we could "translate" the exception name (which is limited as a
python name). EG. RuntimeError -> Runtime error. Of course, this is not a
big deal, but it would let us show the error message to the user, together
with the exception.

It would be much harder to search for an error or ask for help if it was a
message written by some random developer.

OpenERP for example shows stack traces to the user. It could show a shorter
message in the user's language.

I think that would be a job for a per-language team as opposed to someone
implementing a bug fix or pushing a PEP? Even that would only be necessary
for the exceptions a module raises.

That is worse than saying, "why don't we all just code in python?". Or c.
Or java. Or JavaScript.

Let's not get into that. I prefer len() to new
LengthCalculatorFactoryBuilder().createLengthCalculatorFactory().createLengthCalculator().calculateLengthOf().
And a good old Python list or JavaScript array to a collection of segfaults.
