...or if you REALLY want to make sure 'eq' is used for the test.  Usually this
is only important when testing operator overloading.

is() doesn't always use 'eq'.  For example, it will consider "" and undef
different.

    is( "", undef );            # fail
    cmp_ok( "", 'eq', undef );  # pass

is()'s extra logic is usually what you want.
