I'd just like to point out that S03 is back-arsewards here - it
explains === first, and then explains eqv in terms of ===. Since eqv
is the familiar thing people will want most of the time, and === is
the weird thing that isn't used very often, it would make far more
sense to explain them the other way around (and probably confuse less
people). Understanding === should not be a prerequisite for
understanding eqv.
