I'm unsure about changes like this because it makes the code less explicit and harder to read. In fact, I'm not even sure if this line works? I'm assuming it does if you submitted the change.

Thank you again for these suggestions! I do like some of them (as noted in the line-by-line comments), but I err toward a longer and more explicit way of writing code to make it easier to read.
