I don't think so -- that would stop me from being able to point out the errors in a regex my own way.

I add the (?:...) around it for several reasons. First, to honor any of the /imsx switches you have on. Second, so that the regex has ONE root node (easier to parse). Third, so the regex is "its own regex". (That third reason is probably lame.)
