Relative pointer comparison is unspecified unless the pointers point to
different members of same object/array (or if they point to functions).
It's also unspecified if only one of the pointers is null. ( § 5.9 ad 2.)
std::less<> specifies an exception in § 20.8.5/8: "For
templates greater, less, greater_equal, and less_equal, the
specializations for any pointer type yield a total order, even if the
built-in operators <, >, <=, >=do not."
It's an interesting world :)
