Then I am willing to accept the true general case, that which myself
as a human can generally determine by looking at the code and explicitly
seeing the few exceptions a function might throw.

I always assumed I would accept caveats, as I do when using PyChecker or
Psyco. I do not mean to report exceptions thrown from eval or related.

I believe there exists a subset of the apparent infinite possibilities
which can be reported and which would be utterly useful. ;-)
