Oh, I mistyped. I did not mean to add that colon.
Use of "*" and/or "," leads to copying, but we may want to rethink how that
works. *only that level* is copied. If there are references in there to
deeper levels, those levels are not copied. I have to think if there is a
straightforward way to do a deep copy. Right now it's a bit of a mixture.
