Folks --

  We've now degenerated (largely my fault!) into complete
abstraction.  Fun, but useless.

  We all agree that breaking compatibility (source or binary) is bad.
I hope we all agree that *sometimes* it is the best path -- if it
permits better optimizations, better stability, faster release cycles,
etc.  We have to take each of these things case by case; there's no
other way.
