Fair enough, but for those cases, one could just as easily deepcopy the
object in the test itself. Again, it's more explicit, gives the developer
control over exactly what they want to happen, and makes failures more
obvious.

I suppose if the API allowed one to mix and match approaches for different
tests and model objects (like Simon's testdata app does right now), that
would work, too.
