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.
