Not 100% sure here, but since the string is a regular expression, consider
using qr/expression/ without the quotes. The qr/ and / act as the delimiters
and tell perl the contents are a regular expression and thus \s is valid in that
context.
I thnk it may also pre-compile the regular expression so your code runs faster..
