Uh... I don't think they are talking about "beginner C++ programmer"
tutorial. Rather, "beginner to Boost signals" tutorial.

If you are using a library like Boost, it can be safely assumed that you
know your way around C++ already.

Writing a functor (iow. an object that behaves like a function) should be
trivial at that point.

What exactly is the problem with them?

(They are used there just for brevity. You could just as well use a class
if you want. In simple cases a struct will do just fine on itself, though.)

As said, if you are using a library like Boost, one could assume you are
already fluent in C++, and that functors are as trivial to you as plain
functions.
