__examples

[:`is_rvalue_reference<int&&>` inherits from `__true_type`.]

[:`is_rvalue_reference<int const&&>::type` is the type `__true_type`.]

[:`is_rvalue_reference<int const&>::type` is the type `__false_type`.]

[:`is_rvalue_reference<int (&&)(long)>::value` is an integral constant 
expression that evaluates to /true/ (the argument in this case is
an rvalue reference to a function).]

[:`is_rvalue_reference<T>::value_type` is the type `bool`.]
