// This is my approach to creating callable objects
// that correctly reference their object members,
// without messing with prototypes.

// A Class that extends Function so we can create
// objects that also behave like functions, i.e. callable objects.
class ExFunc extends Function {
  constructor() {
    // Here we create a dynamic function with `super`,
    // which calls the constructor of the parent class, `Function`.
