 I miss typedef. I think this is exactly what typedef was intended
 for. Perhaps we can reintroduce it as a 'short hand' for such a
 struct?


 struct Typedef( T ) {
   T payload;
   alias payload this;
 }
 
 Usage:
 
 alias Typedef!( int ) myInt;
 
 Is this what you want?


 Using alias you loose all type safety.
 
 I remember Andrei mentioned that he and Walter couldn't agree
 whether typedef should behave as a sub or super class. I think it
 should not be looked at from a inheritance perspective, but just
 consider it as wrapper struct with a ctor that takes the
 underlying type.


I think you may misunderstand what the "alias this" construct does. It does
exactly what you ask for:
