The standard comparison function objects are partially specialized for std::experimental::propagate_const<T>.

Let p.t_ denote the pointer-like object wrapped by a std::experimental::propagate_const<T> p, then given objects p and q of type std::experimental::propagate_const<T>, the following shall hold:

[edit] Notes

These specializations ensure that when T is a pointer type, specializations of these class templates for std::experimental::propagate_const<T> yield a total order, even if the corresponding built-in operators do not.
