Create a `variant` object holding a contained value of type (template parameter) `t_TYPE`, direct‐initialized from the specified `args`. If this `variant` is allocator‐aware, the currently installed default allocator is used to supply memory. This constructor participates in overload resolutionly if `t_TYPE` designates a unique alternative and is constructible from `args`. For simplicity of implementation, this method differs from the standard in the following way: * `constexpr` is not implemented
