Will do. I'd like to cover the following:
- roadmap for deprecating string exceptions (i.e. when will we issue
 DeprecationWarnings, when will they become illegal).
- roadmap for requiring exceptions to inherit from Exception (or
 discussion on whether this is still a goal).
- impact of the transition to new-style classes everywhere on the
 exception rules.
That might be too broad or too narrow -- I'm up for suggestions!
