... \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.

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` [download] And it sounds like replacing .? with [^;]? was tried.	[reply] [d/l]
