The actual value comparation implemented by PH7 Engine is trying to imitate PHP behavior. First of all, NULL < -1, and NULL == 0. Sorting is thus nondeterministic. Secondly, objects compare as greater than anything else except other objects, which they are neither less than nor greater than. Finally, comparison operators try to sort arrays, two different ways: first by length, then by elements. If they have the same number of elements but different sets of keys, though, they are non comparable.

This needs comparation mechanism to be rewritten and fixed.

We should not compare incompatible values in general.
