this is exactly my complaint about house district names

I've seen that U of T's CSC 110 takes this further and they do it in Python. They do type checking but they also have students write preconditions and invariants that are enforced by their autograders.

CS 135's contracts come from htdp.org, so any course that's based on htdp will have them. One can extend this idea to actually enforce them. We used to do this by using the Typed Racket and turning contracts into actual type annotations.

this is going to get even Cooler as students' writing styles converge on generic LLM voice more
