I think that << and >> almost certainly belong there, and I was kind of 
surprised that <functional> doesn't define function objects for them. Next 
in line would be unary plus.

I'm less sure about the various op-assignments and ++/--. At the moment I'd 
be inclined to skip them. And of course op= is impossible to add because it 
must be a member.

As for <=>, I admit I haven't considered it at all. I haven't yet updated my 
thinking to C++20.
