Actually, this is one exception. I tend to parenthesize any case where
there's a complex set of conditions and mixed AND and OR operations.
Part of the reason for this is that any expression that can be
affected by the precedence of and and or will most likely be fairly
long and/or complex anyway, so a few extra parens won't hurt.
