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!
