Events/C

STATUS: PROPOSAL

Based on Events/A:

without event objects, so stopping propagation or default actions is not possible
renaming Signal to Emitter and Emitter to NameEmitter
addition of emitter method to NameEmitter

Proposal

Emitter(defaultAction_opt Function, dismiss_opt Function): creates an emitter with an optional default action and an empty observer array.
observe(observer Function) Emitter: creates a new Emitter from the given action and a dismissal function, and pushes that emitter onto an internal array of observers. The dismissal function, when called, removes the child emitter from the parent emitter's array of observers.
emit(...args) Undefined: calls each observer's emit method with the given arguments, and then calls and returns the result of the default action with the given arguments.
dismiss() Undefined: if the emitter was constructed with a dismissal function, calls that function. Otherwise, does nothing.

observe(name String, observer Function) Emitter: gets or creates an internal emitter with the given name. Calls and returns the result of the "observe" method on the internal emitter, passing the given observer function.
emit(name String, ...args) Undefined: gets or creates an internal emitter with the given name. Applies and returns the result of the "emit" method on the internal emitter, passing the rest of the arguments.
emitter(name String) Emitter: gets or creates an internal emitter with the given name and returns that emitter object.
