Oh, that's by no means a waste of time --- we need some examples to help
us figure out where the pain points are.  I'm just saying that the best
ways to do things will probably change quite a bit as we introduce
solutions for the pain points.  And I don't intend to be too concerned
about preserving backwards compatibility at this stage.
