And also use them is case/switch statements
where missing values generates compiler errors ?

as in

procedure junk1 is
  type Junk_Type is (One, Two, Three);
  Junk  : Junk_Type := Junk_Type'Last;
begin
  case Junk is
    when One => null;
    when Two => null;
  end case;
end Junk1;


gcc -c -x ada junk1.ada
junk1.ada:10:03: missing case value: "three"
gnatmake: "junk1.ada" compilation error
