As a learning exercise, it is fantastic. Those tests have limited information value: they either work or they do not work. Without a lot of post-test study, we don’t necessarily know why. This is not to say these coarse tests are without information value. Indirect tax? They are special stones with a lot of potential.

We want a way to enable checking for some assertions but not others in the same code, because we may not always be able to afford expensive checks. That’s true whether we’re enabling checking at test time (e.g., on the developer’s machine) or at run time (e.g., in production). Can you see why?
