in thread regex gotcha moving from 5.8.8 to 5.30.0?

There may be a way to do it without all the backrefs.

I don't understand. There don't seem to be any backreferences in any of the regexes presented so far. Can you please clarify?

Give a man a fish:  <%-{-{-{-<

    Bad terminology. I mean the \G having to refer back to the last match.

      ... \G having to refer back to the last match.

      IIUC, the \G anchor refers to the pos of the string against which the match is being attempted (the pos from a previous, unsuccessful match attempt having been preserved by the /c modifier), and so should should be pretty cheap/quick. Is your experience otherwise?

        No, but it's a regression, and seems to be narrowed down somewhere in: 
        $text =~ /\G \s* ^ \s* begfoo \s+ (\S+?) \s* \( \s* (.*?) \s
+* \) \s* ;/gcmsx

        And it sounds like replacing .*? with [^;]*? was tried.
