/**
* If the Object prototype is frozen, the "toString" property is non-writable. This means that any objects which inherit this property
* cannot have the property changed using a "=" assignment operator. If using strict mode, attempting that will cause an error. If not using
* strict mode, attempting that will be silently ignored.
*
* If the Object prototype is frozen, inherited non-writable properties can still be shadowed using one of two mechanisms:
*
* 1. ES6 class methods: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes#methods
* 2. Using the `Object.defineProperty()` static method:
* https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/defineProperty
*
* However, this project uses Babel to transpile ES6 classes, and transforms ES6 class methods to use the assignment operator instead:
* https://babeljs.io/docs/babel-plugin-transform-class-properties#options
*
* Therefore, the most compatible way to shadow the prototype's "toString" property is to define a new "toString" property on this object.
