I'm not really sure, but I have feeling the switch/case advantage is
marginal (am I right?). And another thing I'm not sure of is whether
this must be the case with all compilers. If not, then I think I prefer
a good algorithm to relying on compiler optimization which might not be
so good in compilers other than those tested in this test.

But that's just me...
