This is fantastic. I had never even thought about converting subclasses to functions.

That was super interesting. Thanks a lo!

Now I understand why in Part 1 you didn’t also inline the names of the items (a Brie always had name=“Aged Brie”).
So I learned that if you want to end up with a more functional solution, with an intermediary polymorphism refactor step, you don’t want to touch the constructor of the base class.
I have to say, watching you slowly cut and paste instead of using inline magic, has made me rethink my usage of shortcuts when pair programming with people I know aren’t fluent with them.
