I've had another idea: give unittest_w.TestCase_w a metaclass that
looks for methods called 'test_app_whatever' and arrange for such
methods to be called as objectspace methods.

So, e.g. 

    def test_trivial(self):
        x = self.codetest('''
def g(): return 42''', 'g', [])
        self.assertEquals(x, 42)

becomes:

    def test_app_trivial(self):
        def g():
            return 42
        self.assertEquals(g(), 42)

I have an implementation of this (attached), but it was significantly
more of a pain than I would have liked (mostly because 2.2's unittest
doesn't cope with TestCase classes being new-style...).

It also only works in the standard object space, and only really works
there by fluke (it's the self.assertEquals business that casues the
problems -- can probably try harder and come up with a better solution).

Cheers,
M.
