Similar to `any`, this class can also be used to create _aliases_ for unmanaged
objects either upon construction using `std::in_place_type<T &>` or from an
existing instance by means of the `as_ref` function. However, unlike `any`,
`meta_any` treats an empty instance and one initialized with `void` differently:
