         abstract <T extends Any> Integer compare(KClass<T> targetType, T first, T second)

        Like Comparator but night return null as an indication that comparison can't be performed, e.g. when we try to compare null and not-null.

        Note: exact logic is specific for the type and business use-case, for example, sometimes we might want compare(null, "") to return 0
