Hmmm, so why is this being done *inside* the class definition of TestCase,
because non-singleton methods defined there can only have receivers of
TestCase anyway? What extras do you get?  Doing this outside has its use
like your getSomeSleep example; I can see that.

Oh. Ok I will explore this some more....

Yes, that is nice to have.
