[IronPython] Announcing IronPython 2.0 VS10 CTP

[Dody Gunawinata]

I think this says it all = Duck Typing, Tuple, Open Class, method_missing ..

class C
{
    public dynamic myField;
    public dynamic MyProp { get; set; }
    public dynamic MyMethod(dynamic d)
    {
        return d.Foo();
    }
    public delegate dynamic MyDelegate(dynamic d);
}


and this IDynamicObject interface

public class MyDynamicObject : IDynamicObject
{
  public MetaObject GetMetaObject(Expression parameter)
  {
    return new MyMetaObject(parameter);
  }
}

and meta object overrides

public class MyMetaObject : MetaObject
{
  public MyMetaObject(Expression parameter)
    : base(parameter, Restrictions.Empty)
  {
  }

  public override MetaObject Call(CallAction action, MetaObject[] args)
  {
    Console.WriteLine("Call of method {0}", action.Name);
    return this;
  }

  public override MetaObject SetMember(SetMemberAction action,
MetaObject[] args)
  {
    Console.WriteLine("SetMember of property {0}", action.Name);
    return this;
  }

  public override MetaObject GetMember(GetMemberAction action,
MetaObject[] args)
  {
    Console.WriteLine("GetMember of property {0}", action.Name);
    return this;
  }
}
