This style of code just saved me lot of code duplication and it saved me
alot of complex boolean evaluations. So my concrete code looks good
already. Nevertheless my code would rock much more, if I knew Mono
processes it efficently. ;o)

+It's something that is very easy to add (in a platform-independent
+way, since a negation is always cheaper than a multiplication), but
+note that, unless the jit can determine foo is a constant (or at least
+non-zero) the optimization can't be applied to your code.
+Also note that the condition of the for loop looks wrong, too.
