in reply to Capturing parenthesis and grouping square brackets

Sometimes, change is good. But for something as entrenched as fundamental Perl regular expression syntax, that change has to be really good.

Even if we were inventing regular expressions in a vacuum with no existing code out there (which we most certainly are not. I wonder what point size it would take to stretch all of the capture brackets in current production code, end-to-end, to the moon...), I'm not convinced. I type (?:) a lot less often than I type (), so I believe the shorter code should support the more common case, as has been a long-standing design tenet of Perl.
