I'm sorry I forgot! This thing keeps coming up for me and driving me nuts but I knew I asked in passing before.

So "reference to procedure" are going to be the new standard? To extend my example it would look like this? I please remind me, is there a closure involved which is capturing state and adding overhead?

I'm curious what this type actually is also, maybe a dispatch table which wraps the existing types or is it something totally new?

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

type
  TMyAction = reference to procedure;

procedure DoThis(action: TMyAction);
  begin
    action();
  end;
