Hi Joaquín,

I will try to send both patches and updates to the test. Regarding to the
documentation perhaps we should work together.
Casually, one of the first changes I thought implement is emplace, I was
not aware of the problem you mention.
I will check the design decisions taken in Unordered and Container, in any
case we can discuss it.

Thank you very much for your advice and keep in touch.
Fernando Pelliccioni.
