Начали писать серию статей по NemerleWeb, и там понадобился макрос, который сделал бы объявление типов более лаконичными.

На данный момент первый пример — это классический todo список. Для такого списка неплохо было бы создать тип:
public class Task
{
   public Name : string { get; set; }
   public Priority : string { get; set; }
   public IsDone : bool { get; set; }
}

  public class ReactiveToDo
  {
    [Dto] public class Task { Name : string; IsDone : bool; Priority : string; }

    mutable _tasks = List.[Task]();
    mutable _todoName = "New task";
    mutable _todoPriority = "high";
  
    public this()
