Thanks Matt for your message and for its technical details.

I hasten to point out, however, that what *I* suggested is different and 
much
more simple, while conforming (I hope so!): simply expand with two different
factors inside the constructor from input iterators and during the following
use of the container. Not a big deal, after all. Just a small idea.
