Now, it is my habit to always use quotation marks, just in case. I recommend it as a safer programming practice. As a comparison, it is usually recommended to declare all your variables local (whenever it makes sense to do so), even if omitting LOCAL doesn't create conflicts in
most cases (I got into trouble with variable "i" a few years ago, used in:
FOR i = 1 to ...)
