The code consistently treats the op<() argument as the LHS and *this as the RHS, so it actually implements greater-than. Nothing that needs changing, as the docs don't promise anything and it's perfectly fine to implement op< using greater-than semantics, if done consistently, but worth nothing, because it may raise eyebrows, as it did in this author. Amends the start of the public history.
