I can see why they might expect that.  I can also see why they (or I) might WANT that.

Suppose I've got a long homework assignment with thirty different functions and several
test cases for each, and I'm in the middle of debugging function #25.  What workflow would you recommend?  True, it's not much hassle to keep running old working test cases (unless they take a long time, which is rare), but what if I want to use the Stepper to debug function #25?

One answer is to comment out all the already-working functions, and use the Stepper on the one I care about... except that it uses a helper function that I just commented out.  So I need to uncomment that one, and the global "variables" (i.e. constants) that it refers to.

It would be a whole lot nicer to insert
in the code, or perhaps to wrap a bunch of lines of code in
(with-tests-disabled ...)
(with-tests-enabled ...)
