[Boost-users] [Bind] creating a functio

I'm in the process of figuring out how to use the bind library. The section on operators seems to me missing the "," operator. I see || and && operators which would seem well suited to wrapping a few functions into one - but these would only work for functions returning a bool. How can/should one proceed to get the same functionality of && with function objects which return void? It looks to me that the "," operator should be in there. Robert Ramey
