11   template <class T>
12   struct is_nothrow_move_constructible : public __tof {};
13
14__inherit If T is a (possibly cv-qualified) type with a non-throwing move-constructor
15or a type without move-constructor but with non-throwing copy-constructor,
16then inherits from __true_type, otherwise inherits from __false_type.  Type `T`
17must be a complete type.
18
19In other words, inherits from __true_type only if expression `T(std::move(variable1))`
20won't throw (`variable1` is a variable of type `T`).
21
22__compat If the compiler does not support partial-specialization of class
23templates, then this template can not be used with function types.
24
25Without some (C++11 noexcept shall work correctly) help from the compiler,
26`is_nothrow_move_constructible` will never report that a class or struct has a
27non-throwing copy-constructor; this is always safe, if possibly sub-optimal.
28Currently (February 2013) Clang and GCC 4.7 have the necessary compiler support to ensure that this
29trait "just works".
