 In this example code ''<-'' denotes asynchronous message passing. The message passing semantics is as follows: if the ambient reference is unbound when it receives the ''print'' message, the message is //buffered// and kept for later forwarding; if the ambient reference is bound, it immediately forwards the message to its bound service object. Using these basic parameter passing semantics, a programming may safely abstract from the internal state of the ambient reference: even if the reference is unbound at the time it receives the message, it is smart enough to store the message and forward it whenever a matching service is found.
-One may wonder how return values can be acquired from such asynchronous message sends. We use the concept of a **future**, which is a very well known concept that unifies asynchronous message passing with return values. More specifically, the futures employed in the language AmbientTalk are based on the non-blocking futures of the [[www.erights.org|E programming language]]. For more details, we refer to the paper below, but as a teaser, here's how one can notify the user when the print job has been sent:
