+__inherit If T is a (possibly cv-qualified) type with a non-throwing assignment-operator
+then inherits from __true_type, otherwise inherits from __false_type.  Type `T`
+must be a complete type.
+
+__compat Either requires C++11 `noexcept` and `decltype` or else some (unspecified) help from the compiler.
+Currently (June 2015) compilers more recent than Visual C++ 8, GCC-4.3, Greenhills 6.0, 
+Intel-11.0, and Codegear and all recent GCC versions have the necessary compiler __intrinsics to ensure that this 
+trait "just works".  You may test to see if the necessary support is available 
+by checking to see if `defined(BOOST_HAS_NOTHROW_CONSTRUCTOR) || (!defined(BOOST_NO_CXX11_DECLTYPE) && !defined(BOOST_NO_CXX11_NOEXCEPT))` is true.
