Perhaps a way to use a procedure as a function, now that functions can 
have in/in-out parameter modes. Maybe with syntax like:

  Procedure Y( Input  : in     In_type;
               State  : in out State_Type;
               Output :    out Out_Type );
  Function X renames Y with return Output;

-- Function X being roughly equivalent to the following:
  Function X ( Input  : in     In_type;
               State  : in out State_Type)
               return Out_Type is
  begin
   Return Result : Out_Type do
     Y( Input => Input, State => State, Output => Result );
   end return;
  end X;
