In its original (trunk) form, the test passes with the FakeModule
class system. When I use my manuel fake module version on the test, it
fails - (I think it finds the context object 'A'). I don't quite
understand why at the moment! I *need* to get to the bottom of this
before I can be sure of my work, so I'll take a fresh look tomorrow.
