/*
 * Here is an implementation of an NPM module I recently wrote, done with ES6 classes.
 * Is it a "betrayal" of the prototypal nature of JavaScript to use classes? Come on.
 * Classes are a very common design pattern that's easy to implement with prototypes.
 * And for some use cases, they're a good fit. Node's EventEmitter abstraction is a
 * perfectly reasonable use of classes and inheritance: it's an abstract datatype that's
 * user-extensible. So the 'events' module provides a base class with some built-in
 * functionality that you can extend.
 *
 * And yes, it's a "class." Just check the docs:

//----- Example code:

    // Class declarations:
    // - No data properties allowed
    // - Future: support mixins
    // - Optional: call the initialization method `new` instead of `constructor`

    // Superclass
    class Person {
        constructor(name) {

var originalNodeListProto = NodeList.prototype;
var temporaryNodeListProto = Object.create(NodeList.prototype);
temporaryNodeListProto.a = 1;

NodeList.prototype = temporaryNodeListProto;

var l = document.querySelectorAll('a');
console.log(l.a); // inherited from which prototype?

NodeList.prototype = originalNodeListProto;

    Object.keys(this).forEach(function(key) {

    }.bind(this));

});

var obj = {a: 1, b: 2};

// A Dict class that works in ES6 using Map. Basically it's identical to Map, but
// only expected to be used on string keys.

function Dict() {
    this.elts = new Map();
}

// (string) -> any
Dict.prototype.get = function get(key) {
    return this.elts.get(key);
