You could use the new function_traits library, but that's not in a

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!
