Indeed, the most important reason for which I added chaining was its
everyday usefulness. As I also wrote in the book, I decided to stop
there before adding much more features like Chain, because they drift
away from Functor's charter.

On the other point about Loki::Functor's constructor taking an object
and a pointer to member function: the bind() function does the same,
so it's all right as it is. I do like the constructor for the sake of
purity: everything that can be called like a function ought to be
accomodated as a constructor of Loki::Functor.
