If you want to associate your literals with bit patterns,
you could do, similar to the 83 Rationale suggestion
<http://archive.adaic.com/standards/83rat/html/ratl-15-05.html#15.5>:
(I don't know Ada, so pardon if this isn't quite right).

     PermissionsPatterns: constant array(Permissions) of Integer :=
         (Read => 2#0001#, Write => 2#0010#);

But when you go around telling the compiler that it should
actually represent Read as 2#0001# and Write as 2#0010#,
you're not going to convince me that this isn't treating
enumerations as if they are integers.

Hey, can I do this? If not, why?

     Type Constants is ( Pi, E, Phi );
     For Constants use record
         Pi  => 3.141592654,
         E   => 2.718281828,
         Phi => 1.618033989
     end record;
