[Boost-users] self-referential boost functions

Inquiring as to whether this is possible or if there is a better pattern for simulating this behavior... Is it possible for boost::function to be self referential? I.e. how do I simulate behavior like the following: typedef boost::function<Func (int)> Func; A function that does something mutable and then returns the next function to be called or an empty function. thanks, Adam
