You could use the new function_traits library, but that's not in a
release yet. Or recreate the type "manually" using the component
typedefs in function http://boost.org/doc/html/boost/functionN.html.
I just created my own quick little class for this:
template< typename t_fun >
    class FunctionHolder
     {
    public:
         typedef t_fun type;
    };
I don't understand why boost::function can't just have the following:
typedef Signature signature_type;
It would be very useful!
If you're only using boost::function, you could do something along the lines of

template<typename T>
struct signature;

template
struct signature >
{
  typedef Signature type;
}

// is_same >::type, void(int)>

If you're using boost::functionN classes directly, you'd have to
recreate it like Rene is suggesting.
