- [:`is_lvalue_reference<int&>` inherits from `__true_type`.]
- [:`is_lvalue_reference<int const&>::type` is the type `__true_type`.]
- [:`is_lvalue_reference<int const&&>::type` is the type `__false_type`.]
- [:`is_lvalue_reference<int (&)(long)>::value` is an integral constant
- expression that evaluates to /true/ (the argument in this case is
- a reference to a function).]
- [:`is_lvalue_reference<T>::value_type` is the type `bool`.]
