Hi Corion, thanks for the reply. What do the ! mean instead of the normal / in the regex?

My opinions may have changed,
but not the fact that I am right

    They don't mean anything special, you can replace the '/' with any other character (or matching pairs of brackets) to improve readability and reduce the requirement for escaping of literal '/' characters in your expression.

    The ! are used as alternative delimiters, because you use / within the regular expression. This makes it easy to avoid the escaping of slashes. Instead of \/, I now can write / as it will not be recognized as the regex delimiter anymore.

    perlop has the section on Regexp Quote-like Operators which explains how this works.
