How would you do this automatically? It is better to bind a variable by value because there is no garanty that your bound variable is still valid if it would be bound by reference.
The compiler can't deduce whether you want to bind the variable by reference or by value.
Only you know and you have to make that specific in a way; the way in sigc++ (and also boost) is to use ref().

But with the documentation I agree :)
