There seems to have been some misinformation somewhere, try
this:

with Ada.Strings.Unbounded;
with Ada.Text_IO;

procedure v is

   use Ada.Strings.Unbounded, Ada;

   x: Unbounded_String := Null_Unbounded_String;

begin
   x := x & "Hello";
   x := x & "World";
   Text_IO.put_line(to_string(x));
end v;
