Thanks, to you and the dudes above sharing their wisdom! perl -v yielded 5.8.0. The info page said it was for 5.6.1. Now that I know this simple trick, I'll be able to be more accurate in my titles.
As to the code, yup. I'm missing the backslash before the 'W'. Hopefully I'll become more adept at catching these errors as time goes on and my experience builds.
