Coding: How to Evaluate A Parse Tree

In this video we are going to begin writing the bones for our parse tree evaluator. This is when our language really begins to come alive and we can begin to really have fun with our language.
There are many strategies for evaluating an AST, which we will cover here. However, we will opt for the simple tree-walking strategy that has given so many popular languages their start. Hope you enjoy it!

Excellent.

Just nitpicking: There is a copy error at 3:30. The type of the Boolean value should be "Bool(ean)" instead of "Integer". Nevertheless: I liked this video very much!
