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! -Barry
