No need for the backslashes, just use single quotes. :-)

While restricting split to just strings might be useful it would not be
nearly as useful as using regular expressions. On the other hand, how
would you join on / +/? Is that one space, ten spaces or a thousand
spaces? If you join using /\w/ which of the 63 letters numbers and
underscore characters (more if "use locale" is in effect) should join
use?
