Boost.Compat is a repository of C++11 implementations of standard components added in later C++ standards. Its target audience is Boost library authors whose libraries support a lower C++ standard, but wish to utilize a component added in a subsequent one.
The criteria for inclusion in Boost.Compat are as follows:
using declaration in case the standard component is
available.boost::compat
type; the use of Compat types should be confined to library
implementations.
