Walnut/Distributed Computing - Erights

Eventually Operator

All distributed computing in E starts with the eventually operator, "<-":

 # E syntax
 pragma.syntax("0.9")
 car <- moveTo(2,3)
 println("car will eventually move to 2,3. But not yet.")

Promises

When you make an eventual send to an object (referred to hereafter simply as a send, which contrasts with a call
to a local object that waits for the action to complete), even though
the action may not occur for a long time, you immediately get back a
promise for the result of the action:

 # E syntax
 def carVow := makeCar <- ("Mercedes")
 carVow <- moveTo(2,3)
