Previous commit changed DOM fragment representation to use strings instead of Seal'd quasi-sexprs, and so eliminated any distinction between textually-identical DOM fragments in the dataspace. This patch disables the "spawn" buttons for components in the IoT demo to avoid (mostly harmless) duplication of actor instances. It also demonstrates use of react{} outside a *lexically*-enclosing actor{}. |

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.
