Detailed Description

template<class T>
class mundy::storage< T >

Storage policy for T:

• if T is (or refers to) reference_wrapper<U>, store reference_wrapper<U>
• else if T is (or refers to) a pointer type U*, store U*
• else if T is an lvalue reference U&, store reference_wrapper<U>
• otherwise, store std::remove_cvref_t<T> by value
