JavaScript Callable Object using callee

index.js

'use strict'

class Callable extends Function {
  constructor() {
    super('return arguments.callee._call.apply(arguments.callee, arguments)')
    // We can't use the rest operator because of the strict mode rules.
    // But we can use the spread operator instead of apply:
    // super('return arguments.callee._call(...arguments)')
  }
  
  _call(...args) {
    console.log(this, args)
  }
}

Remove 'use strict'; since this does not work in strict mode.
