My understanding is that if you do

    t = True
    nil = False
    assert t == nil

in py.test, the error reporting will show you "t != nil (True != False)" or somesuch, along with a bunch of other useful diagnostic information.

My proposal was to steal this by doing 'self.failUnless(t == nil)' and stealing as much of their stack introspection junk (available as a hacked version of AssertionError) as we can.
