That would be very useful.

As an aside... in addition to this I often find myself creating two
container collections over and over again...

The first is a map and hash_map for ordering and fast look up. The
second being a vector for a fast direct repository and other containers
for lookup / indexing.

There is a container composition / indexing library waiting in those use
cases somewhere wanting to fall out...

I read this mail in the midst of doing what boils down to the second
common usage yet again...
