Raymond Hettinger added the comment:
I would also like to see a PEP or good python-dev discussion before embarking
on all these API expansions. There should be an evaluation of whether any
existing code would benefit from it, whether the current "args" attribute is
sufficient, whether the code bloat is worth it, etc.
Also, I'm unclear on whether you expect users to have to provide the index
value in their own code (i.e. is "raise IndexError" to still be permitted or
will all pure python code be required to use "raise IndexError(i)" and change
existing code if they already use "raise IndexError("Out of range")).
If you don't change requirements for pure python code, then how can be even
rely on the new attribute being there (i.e. is "except IndexError as e:
print(e.index)" guaranteed to work?).
