So I find myself wondering why you'd ever use %lookup? Why search the
array when you can simply add 1 to a number? Not only is adding more
obvious to the person reading the code, it's also much more efficient
for the computer.

Another consideration, which I don't think would be a concern for this
specific situation, but definitely applies when thinking about the
concept in general ...

If your lookup value is a valid array element value, you can overwrite
an element. The +1 method eliminates this possibility.
