// We can't write a rigorous test if the struct name or signature changes dramatically,
// but if the student implements `Set[T comparable]`, we can instantiate it here.

// BUG: To compile the test file out-of-the-box before the student finishes the exercise,
// these tests are heavily commented or rely on reflection if we wanted to be tricky.
// Instead, we provide the test code. When the user refactors `ex01_set.go`,
// they must also uncomment this test to prove it works!
