Yeah, there are a number of workarounds.  Using partial, def-ing a
function, or using a lambda will all work.  My point was that, with
the right API, these workarounds wouldn't be necessary.  Look at
unittest.TestCase.assertRaises to see another example of the kind of
API I think should be supported (when possible, of course).
