  Syndicate is a new coordinated, concurrent programming language. It occupies
a novel point on the spectrum between the shared-everything paradigm of threads
and the shared-nothing approach of actors. Syndicate actors exchange messages
and share common knowledge via a carefully controlled database that clearly
scopes conversations. This approach clearly simplifies coordination of
concurrent activities. Experience in programming with Syndicate, however,
suggests a need to raise the level of linguistic abstraction. In addition to
writing event handlers and managing event subscriptions directly, the language
will have to support a reactive style of programming. This paper presents
event-oriented Syndicate programming and then describes a preliminary design
for augmenting it with new reactive programming constructs.
