Class alias for class helper doesn't make class helper visible for compiler.

Class alias for class helper doesn't make class helper visible for compiler.
Is it possible to declare class alias for class helper with making class helper visible for compiler?

 

Example 

Unit1

  TControlHelper = class helper for TControl
    function RefSelf: TControl;
  end;

Unit2
  TControlHelper = Unit1.TControlHelper;

Unit3
  uses Unit2;
...
  var MyControl: TControl;
  MyControl.RefSelf //Compiler error.

 

[Wak 1]

The helper is not in the scope because Unit1 is not in the Uses list.

Have you tried

 

unit Unit2;

interface

uses Unit1;

type TControlHelper = class helper(Unit1.TControlHelper) for TControl end;

implementation

end.

 

(Haven't tried myself, but logically, I think it would work)
