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).
