(In particular, the files here .) We aggressively modified that code to suit our somewhat different needs (and taste). Notably, Pierce's code only provides a substitute-and-repeat interpreter; so part of our refactoring was to make it easier to switch back and forth between that and an environment-based interpreter. -We provided you with a [[homework assignment|/exercises/assignment7]] that is a simplified version of the code of our interpreter.

But these benefits come at a price. The code has some complexity to it.
