I'd like to have tuples in Ada and be able to say:

=C2=A0 =C2=A0for (Name, Value) of=C2=A0Environment_Variables.All_Variables =
loop
=C2=A0 =C2=A0 =C2=A0 Put_Line (Name & " =3D " & Value);
=C2=A0 =C2=A0end loop;

In many cases tuple would be handy, avoiding creating record in some
cases just to be able to return two values from a function for example.
