We can also define equivalence on gradual types. Two gradual types ``A`` and
``B`` are equivalent (that is, the same gradual type, not merely consistent
with one another) if and only if all materializations of ``A`` are also
materializations of ``B``, and all materializations of ``B`` are also
materializations of ``A``.
We can also define an **equivalence** relation on gradual types: the gradual
types ``A`` and ``B`` are equivalent (that is, the same gradual type, not
merely consistent with one another) if and only if all materializations of
``A`` are also materializations of ``B``, and all materializations of ``B``
are also materializations of ``A``.
