          Issue ID: 24484
           Summary: Generic container's recursive destructor does not
                    compile due to "no size".
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody@puremagic.com
          Reporter: scrubereal@gmail.com

struct Array(E) {
    E[] elements;

    ~this() {
        foreach (e; this.elements) e.destroy();
    }
}

struct Node {Object value;}
struct Object {Array!Node values;}

> issue.d(5): Error: struct `issue.Node` no size because of forward reference

Actions that suppress the issue:
- removing the line of code in the destructor's body
- changing `~this()` to `void destroy()` and calling it manually
- removing the type parameter and replacing `E` by `Node`
- moving `Object.values` into `Node`.
