Hi Marijn,
The value-now/sync procedure waits for propagation to complete before
reading a signal's value. Would something like the following suit your
purposes?
(define a (event-receiver))
(define b (event-receiver))
(define a+b (+ (hold a) (hold b)))
(send-event a 3)
(send-event b 5)

Hi,
Consider:
#lang racket
(require frtime)
(define a (event-receiver))
(define b (hold a))
(send-event a 3)
;;; uncomment next line to make it work
;(value-now (hold a))
(value-now b)
`a' is an event-stream onto which the value 3 is sent.
Hi Marijn,
FrTime propagates changes asynchronously. When send-event returns, there's
no guarantee that the event has finished propagating through the system.
And in general, (value-now b) is not well-defined, since asynchronous
processing makes it difficult to define what now means; programs
