Subject: [boost] What C++14/1z standard or TS libraries would you like to have available on a C++11 compiler?

I would like to have your feedback on C++ standard library features you
would like to have available for a C++11 compiler.

The idea would be to present a Boost.StdExtensions library that would
provide some of these features for review with some of these features.

Please , let me know if you are interested in participating in this
project and working on some specific parts.

This library should avoid as much Boost dependencies as possible.

How the library could be structured? I believe that it should follow the
C++ standard files.
Which folder should be used? boost/stdext? boost/stdext11?
Which namespace? boost::stdext?

I have prefixed with a * the lines that interest myself and with VBE*
those that I could work on.

The features that need compiler help or that need C++14/17 language
features are excluded and prefixed by N/A.

Please be free to add a * if you are interested and your name as well if
you want to participate.


P.S. The project could be as well extended to C++98 compilers with C++11
standard libraries (But I would not have time to invest in).

P.S.S. I would also be interested in extend the project to extended to
C++14 compilers.
