The former, i.e. forall a and b satisfy a.eql?(b), a.hash and b.hash
should have same values.  But if a.hash and b.hash have same hash
values, a.eql?(b) may not be true.

| This don't work for the first case with [1, 2, [1, 2]] and [1, 2, [1, 2]]

Yes, you are right.  I must think more deeply about how to get hash
values for arrays.  sigh.
