Support capturing with a pattern in the Syndicate/js DSL: ($foo = bar()) Struct has been cleaned up, and now offers proper Javascript objects for its prefab-like structures. These can serialize and deserialize themselves to/from JSON. They behave like prefabs in that two StructureTypes created with the same label and arity behave identically wrt Dataspaces and Tries. Sadly, prefab field names had to go in order to support this. Facets now track and terminate their children upon termination. This is experimental; I suspect it is required for nested durings. DemandMatcher can now support multiple specs, but this is less useful than you might think since it tracks supply and demand quite naively. It would have to have (surprise, surprise!) a mux-like structure to do the job properly! Added WakeDetector to main.js; adding the broker client will have to wait until it is turned into a proper module in the src/ directory. |

Syndicate: A Networked, Concurrent, Functional Programming Language
Syndicate is an actor-based concurrent language able to express communication, enforce isolation, and manage resources. Network-inspired extensions to a functional core represent imperative actions as values, giving side-effects locality and enabling composition of communicating processes.
Collaborating actors are grouped within task-specific networks (a.k.a. virtual machines) to scope their interactions. Conversations between actors are multi-party (using a publish/subscribe medium), and actors can easily participate in many such conversations at once.
Syndicate makes presence notifications an integral part of pub/sub through its shared dataspaces, akin to tuplespaces. Each shared dataspace doubles as the pub/sub subscription table for its network. Actors react to state change notifications reporting changes in a dataspace, including new subscriptions created by peers and removal of subscriptions when a peer exits or crashes. State change notifications serve to communicate changes in demand for and supply of services, both within a single network and across nested layers of networks-within-networks. Programs can give up responsibility for maintaining shared state and for scoping group communications, letting their containing network take on those burdens.
