Is it possible to declare an identical type for a generic class?

Is it possible to declare an identical type for a generic class?

I can't do it.

 

 

  TTypedListFieldLinkEh = EhLib.TableLink.TypedLists.TTypedListFieldLinkEh;
  TListFieldLinkListEh = EhLib.TableLink.TypedLists.TListFieldLinkListEh;
  TTypedListItemLinkEh = EhLib.TableLink.TypedLists.TTypedListItemLinkEh;
  TListRecLinkListEh = EhLib.TableLink.TypedLists.TListRecLinkListEh;
  TListTableLinkEh = EhLib.TableLink.TypedLists.TListTableLinkEh;
  TListFieldLinkListEh<T: class, constructor> = EhLib.TableLink.TypedLists.TListFieldLinkListEh<T: class, constructor>; //Compile Error
  TTypedListItemLinkEh<T: class, constructor> = EhLib.TableLink.TypedLists.TTypedListItemLinkEh<T: class, constructor>;
  TListRecLinkListEh<T: class, constructor> = EhLib.TableLink.TypedLists.TListRecLinkListEh<T: class, constructor>;
  TListTableLinkEh<T: class, constructor> = EhLib.TableLink.TypedLists.TListTableLinkEh<T: class, constructor>;

Thank you. This code works:
 

TListFieldLinkListEh<T: class, constructor> = class(EhLib.TableLink.TypedLists.TListFieldLinkListEh<T>);
TTypedListItemLinkEh<T: class, constructor> = class(EhLib.TableLink.TypedLists.TTypedListItemLinkEh<T>);
TListRecLinkListEh<T: class, constructor> = class(EhLib.TableLink.TypedLists.TListRecLinkListEh<T>);
TListTableLinkEh<T: class, constructor> = class(EhLib.TableLink.TypedLists.TListTableLinkEh<T>);

In this case, however, a new type is created. But for types created through generics this is not a very big problem.
