Interesting, thanks. The concept is not difficult to understand but
I'm not sure it would be preferable. A copy operation should have the

You mean a deep-copy? That is unnecessarily expensive; with a

Shallow copy...
Actually I meant whatever that snapshot operation is, minus the
insertion, if that makes sense.
