Remember, if in doubt, you can always add more parenthesis; not only
does it make sure that Ruby (or any language, really) understands what
you want, it also makes sure that you understand what you want. ;)

I usually do that anyway, to keep myself in check- In any case where i'm
using &&, ||, etc, throw it in a () to make sure my meaning is
understood.
