[Boost-users] [signal] How to disconnect?

From: Boris (boriss_at_[hidden])

void Hello() { }
boost::signal<void ()> sig;
sig.connect(&Hello); 		// OK
sig.disconnect(&Hello); 	// Error

Can anyone tell me how I disconnect the callback function Hello? I can see  
in the documentation that I can call disconnect with a group_type and with  
a slot_type but not with a slot_function_type. I'm surprised to run into  
such a problem as from the point of view of a library user it can't get  
much easier than that?

PS: This is with Boost 1.33.1.
