Description of Problem
----------------------

For a record like :
    
      type MyRecord_type is 
        record 
          Alice : unsigned(5 downto 0); 
          Bob   : signed(9 downto 0); 
          John :Boolean; 
          Adam  :bit; 
        end record MyRecord_type; 
    It would be nice to have an attribute something like this. 
    MyRecord'members which will return (Alice, Bob, John, Adam) 
    
    
    And in the other way around used in a loop 
    For n in MyRecord'members'left to MyRecord'members'right loop 
     If MyRecord.n'member :	 SomeThing then 
       Do this.. 
     Else 
       Do that... 
     End if; 
    End loop;
