Functions are also stateful; C++ isn't a functional language.

Right.

I think the question here is whether instances of functors should
be treated as functions or variables.

IMO, it's clearer if callable types (whether they be functions,
member functions, function pointers, or functors) share coding
style.

I think either choice should be clarified in the coding standards.
