Extract a helper from the factorial unit test: check_ints_equal.

Start of a vocabulary for unit tests.

I *could* also start thinking of supporting multi-file programs, but I'm
going to resist the temptation for now. Copy helpers as necessary, and
allow them to mutate and diverge for a while before we pummel them into
a Procrustean "standard library". Extracting a body of shared code immediately
starts to discourage innovation in the shared code.
