In PHP, a period is the operator to join two strings together. Kind of like glue. I was just thinking that if the description got "glued" to something else, then that would mess up the flow of a script. But, like I said, I've only seen one LL that warns about this on his rules page. In fact he states NO punctuation at the end.
I'm still swimming in the php baby pool, so what I say may likely just be pure conjecture.
