another example:

    void delegate(void*) dg = delegate(void*){ writeln("test"); };
    void delegate(void*) dg2;
    void delegate(void*)[] dgs = [dg,dg,dg,dg];

    //dgs.writeln; // fails
    auto s = "%(%s %)".format(dgs); // fails
    void delegate(void*)[] dgs2 = [null, null, null, null];
    //dgs.writeln; works
    //auto s = "%(%s %)".format(dgs); // works
    moveAll(dgs, dgs2);
    move(dgs.front, dgs2.front);
    move(dg, dg2);
    dg2(null);
