Out of curiosity. Is there an optimization like this

No.
Are you sure? It seems the compiler disagrees with you.
I tested with 2.7.1 (updated yesterday):
function Foo(s:string): string;
begin
Result := s;
Form1.Caption := s;
end;
procedure TForm1.FormCreate(Sender: TObject);
begin
//DebugLn(['abc']);
//DebugLn('abc');
DebugLn(foo('abc'));
end;
The assembler for FormCreate (no optimization used). It even omits
the call to "Foo"...
How is debugln defined?
