       keys() returns an array of keys (indices) corresponding to
       the  keys  in the (key, value) pairs stored in the mapping
       m.

       For example, if:

              mapping m;
              m = (["hp" : 35, "sp" : 42, "mass" : 100]);

       then

              keys(m) == ({"hp", "sp", "mass"})

       Note: the keys will not be returned in any apparent order.
       However,  they  will  be returned in the same order as the
       corresponding values (returned by the values() efun).
