Monks,

I have a set of strings (pulled from a DB) that I'm concatenating into one string, using the following code: 

if ($concat !~ /$string/) {
   $concat .= " and $string";
}

[download]
Simple enough, and it does the job, except where the imported strings contain any form of parentheses, for example () or [], where the string always gets appended regardless of whether it's already there or not.

I'm trying to find a way to escape the strings that are being matched against - does anyone know of a way to do this? I've tried running the string through qq, and tried using /"$string"/ to match, with no success ..

Thanks in advance for your help.
