Generic pointer type to a generic type

[Wak 1]

I've worked with generics quite a bit, but I have never tried to define a generic pointer type to another generic type:

  TMyType<T> = record
    ID: T;
  end;

  PMyType<T> = ^TMyType<T>;            // Error: E2508 type parameters not allowed on this type
  TMyTypes<T> = array of TMyType<T>;   // OK
  PMyTypes<T> = array of ^TMyType<T>;  // OK

  TMyTypeHack<T> = record
    P: ^TMyType<T>;                    // OK
  end;

This raises a compiler error. It seems Delphi doesn't allow type aliases like this, but allows using them in the definition of array/record types. Has anyone found a trick to achieve it? Thanks!

I feel like I seen this somewhere .. maybe even from Marco Cantu .. mentioning that this "hack" was necessary.

 

 PMyType<T> = record
    P: ^TMyType<T>;                   
 end;
