I don't really like the idea of adding a modifier to supress interpolation... Currently there is: $string =~ m/Pattern with a literal \$ sign/; and $string =~ m'Pattern with a literal \$ sign'; Personally, I have never ever used m'' and I don't see a reason to use / n over \. A reason against it: You need to look at the end of the regex to know wheter or not things get interolated. What if the regex is using the /x modifiers and takes 10 lines? Also according to: http://www.regular-expressions.info/refflavors.html JGSoft and .NET are already using the n modifier for an explicit capture which can make it very confusing (for people coming from JGSoft and/or .NET) and/ or for regex tools.
