As you have probably figured out from the responses of others, there is a 
lot of interest but coming up with the right feature set would require some 
thought.

Another desirable feature is filtering. (That is also a need for 
non-recursive iteration.) John Maddock and others did some work on 
filtering a while ago, but then we got busy with other things and didn't 
pursue it.

Very early in the library's evolution there was an attempt to handle 
recursion (for copying, IIRC) via adding a runtime option or two. The 
number of options multiplied, and the approach was dropped as unwieldy.

I wonder if a policy-based template approach might be more appropriate?
