Hmmm. As far as I know you can use _ as a placeholder for a variable, and it's meant for this kind of use (where you don't really want to introduce a new variable name). It's strange that it doesn't work for you. Can you post the error message that you get?
I guess it's not a big deal since you can always use x as you did, but if it's really not working it might be a sign of other trouble.
