Can I just check this - sigc::slot's are what I use in typedefs, as data 
members, and as functon arguments when implementing  an API, and users 
of the API pass  in a sigc::ptr_fun() and sigc::mem_fun() to create 
those slots. The reason I ask is because I found you can pass a 
sigc::slot<> as well and it seems to work ok.
