This extension builds on the work from the previous one and covers Chapter 13 of the book.

By the end of this extension, your interpreter will be able to handle class inheritance, method overriding and the super keyword.

Here’s a sneak peek at what you’ll achieve:

class Doughnut {
  cook() {
    print "Fry until golden brown.";
  }
}

class BostonCream < Doughnut {}

BostonCream().cook();

Please give this a try and let us know how it can be improved! @ryan-gang (author of this extension), and I will be available here to help out with any tester or instruction-related issues.
