Why pairs of tests? What does "(when t 2) 2)" test that "(when t 1) 1)"
doesn't?

It tests that 1 is not the only value for which the macro works properly? 😀

I didn't think much about it, really. My attitude with tests is that
redundancy is approximately 100x better than the risk of not testing
something.
