PEP-290 advises against automated tools for this type of change.
I certainly agree to the need for human review of such changes. I don't think this would be onerous, though (as you've suggested in private email) I should certainly try it myself. [...]
Also, take a look at what would need to be done to the test suite. The changes there are less amenable to an automated update.
I will.
Grep could find most potential changes but I don't see how you can statically determine whether 'raise x' is a class or instance without running the code.
That's true. Certain cases of two- and three- argument raise statements are difficult as well. Rather than discuss it in the abstract, how about I just implement the tool I have in mind and see how well it works?
