Mixed: {
prototype: Mixin & InstanceType<Base>;
new (...args: ConstructorParameters<Base>): Mixin & InstanceType<Base>;
} & { [K in keyof Base]: Base[K] }

}

class BaseClass {
	baseMethod(): void {
		// ...
	}
}

const MixedClass = MyMixin( BaseClass );

// Contains both `mixinMethod()` and `baseMethod()`.
