-An `@add_args` call providing values for all arguments accepts positional arguments like this: `@add_args(5, 6, 7)` (which returns 5 + 6 + 7 = `18`). A call omitting and using the default value for the the final `argument_3` can also use positional arguments: `@add_args(5, 6)` (which returns 5 + 6 + 3 = `14`).
