Features expected to be provided by future C++ standards.

Namespace anticipating some simple features of C++ standards not yet adopted.

It is recommended that whenever all supported compilers support each single feature, that be removed from here, and the standard one immediately adopted.

The aim is that the interface and behaviour here are as similar as possible, so that the update should boil down to a different header inclusion and a different namespace.
