So if we do this there is nothing being captured right? In that case we get an interface which can call a function pointer? Does the interface then know about "of object" and "is nested" types at all or does it use a totally different mechanism to call those?

================

type
 TMyAction = reference to procedure;

procedure MyAction;
 begin
 end;

procedure Test;
 begin
   DoThis(@MyAction);
 end;
