Why don't you just try it yourself?

And there are quite some techniques in that article. which one do you mean? Maybe if you take some more time to formulate your real question?

The article mentions anonymous functions, which are not supported, but are also useless. People asking for anonymous functions almost always mean that they want closures. In Delphi the way to use a closure is through an anonymous function.

My guess is that the answer to your question is no, but for a real answer we need more information.

Unfortunatelly in the moment I have no a FPC from trunk, I will install it as soon as possible.

The doubt shown in the title: "Is "reference to procedure" implemented in trunk?". Eg:

TProc = *reference to* procedure(x: Integer);
procedure call(const proc: TProc);
begin
  proc(42);
end;
var
  proc: TProc;
begin
  proc := procedure(a: Integer)
  begin
    Button1.Caption := IntToStr(a)
  end;
  call(proc)
end;

The article mentions anonymous functions, which are not supported ...

Thanks, it answers my question! ;)

For a moment I thought something like this was implemented, then I would test it.

... but are also useless.

OK, thanks again!
