Thanks, the roadmap looks great.

better abstraction facilities for asynchronous code

I’m guessing this also includes being able to define an actor method in a different file from the actor declaration.

Also, if it’d be possible to have an actor method call another actor method as a helper function but without async, which changes the atomicity semantics as well as (possibly) the latency.

For example,

actor {
    public func foo(): async () {
        let tmp = bar();
    };

    public func bar(): async Nat {
        5;
    };
};

Also, it’d be helpful to have more guidelines on error handling. Option types, throw, trap… it’s not always that clear to me which to use, even after reading this.
