If you can see it, do I really have to be explicit? ISTM that unrolling such
a loop makes eminent sense from a performance perspective let alone a
stylistic one. If one really wants an ordered enumeration of two values, why
not declare it as such? Will it not make the program more readable. After
all, one uses enumerations when integer values work equally well for the
same reason.
