Please feel free to say "I think *this* way would be better because...".
 But please don't just ignore what I've written and propose something
else.  I wrote that email to satisfy your concerns as well as John's,
since you wrote "I second this comment".

I thought your were going to apply your Registry object more or less
directly.  I would like to keep the number of Option classes small, so I
don't think both should coexist.

My solution isn't much farther along.  I've written some stuff I haven't
committed.  I got hung up trying to decide whether to introduce an
ordered dict class, or just stick with a list, since they'll never be
long enough for it to matter.
