Comparing values will be a lot cheaper with ints than strings. So if your
enum type is possibly used in hot loops, ints will be your friend. Also,
with ints, you can provide an ordering that differs from the lexical order
of the string values. For example, with an int, you can easily sort by
day-of-week by defining the constants in order. With strings, you have to
use a custom compare function that acts on string names (ick).
