[X] F2023: "7.5.9 Derived-type specifier" R754 derived-type-spec is type-name [ ( type-param-spec-list ) ] C796 (R754) type-param-spec-list shall appear only if the type is parameterized. C797 (R754) There shall be at most one type-param-spec corresponding to each parameter of the type. If a type parameter does not have a default value, there shall be a type-param-spec corresponding to that type parameter.
