- __inherit If T is a (possibly cv-qualified) type with a non-throwing copy-constructor
- then inherits from __true_type, otherwise inherits from __false_type. Type `T`
- must be a complete type.
- These two traits are synonyms for each other.
- __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_COPY) || (!defined(BOOST_NO_CXX11_DECLTYPE) && !defined(BOOST_NO_CXX11_NOEXCEPT))` is true.
