Re: [Vala] Are nested interfaces disallowed?

ping.

Are nested classes/interfaces officially supported in vala?

Classes seems work fine with vala 0.10 [1], but not interfaces.


1)

public class AClass {
    public class BClass {
        public void print() {
            stdout.printf("Hello, world!\n");
        }
    }
}

void main() {
    var cl = new AClass.BClass();
    cl.print();
}
