Create a `variant` object holding the same alternative (if any) as the specified `original` object. If this `variant` is allocator‐aware, the currently installed default allocator is used to supply memory. If the `original` object is not valueless by exception', the contained value is copy‐constructed from the contained value of `original`. This constructor is deleted unless all alternatives are copy constructible. For simplicity of implementation, this method differs from the standard in the following ways: * conditional triviality is not implemented * `constexpr` is not implemented * `noexcept` specification is not implemented
