Its operator() might as well be a virtual function. The fact that
it's implemented differently is merely a matter of special-purpose
optimization that wouldn't be worth the trouble for the vast majority
of similar classes. I know that won't make an impression on you,
because you don't seem to think there are many similar classes... but
there are.
