[boost] boost::function / boost::signal convenience

Hi,

I'd like to write the "Preferred syntax" of a signal while
including a header for a fixed number of parameters.
This works for boost::function, but not for boost::signal.
Surprisingly, it seems that signal1.hpp does only generate
a signal1 template, in contrast to function1.hpp. :[
Couldn't that be aligned to boost::function?

#include <boost/function/function1.hpp>
typedef boost::function1<void, void> F1; // compiles
typedef boost::function<void (void)> F2; // compiles

#include <boost/signals/signal1.hpp>
typedef boost::signal1<void, void> S1; // compiles
typedef boost::signal<void (void)> S2; // does not compile
