Hi pypy-dev,

We have pypy/lib/_exceptions.py which is a generated applevel
definition and gets translated to pypy/module/exceptionsinterp.py by Christian fine geninterp mechanism. Now to fix some remaining compliancy bugs it seems easy to fix the applevel exceptions definition unless there is a need to still be able to regenerate that as well. I'd guess the latter is not neccessary anymore so is it fine
to just fix pypy/lib/_exceptions.py and regenerate? And what
was the incantation again to regenerate the exceptionsinterp.py again (did i miss some piece of documentation somewhere)?

I think we can continue to generate the exceptions. For migration to future versions, it finds subtle argument additions quite nicely.

The only complicancy problems that I see are the __str__ methods.
There are just a few to be implemented by hand.
A mechanism to supply these methods is inside the generator.
As an example there is already one such method implemented,
see the end of pypy/tool/_enumerate_exceptions.py

About interpleveling the things, I agree with Armin that
this should be cache-generated, soon. Will look into that.

ciao - chris
