/**
 * @mixin - TODO make this @mixin tag do something in the docs.

 * to set multiple properties of an instance at once. See `set()` method
 * description.
 *
 * This class is a mixin. Use it like so:
 *
 * ```js
 * class MyClass extends Settable() {
 *   // ...
 * }
 * ```
 *
 * or
 *
 * ```js
 * class MyClass extends Settable(SomeBaseClass) {
 *   // ...
 * }
 * ```
 */
class Settable {}
