So how can you reverse a regex safely? Try YAPE::Regex::Reverse... ;)
Actually, I've not released it yet. But it works quite well:
jpinyan@sushi [12:42pm] ~ #614> perl rev-test
(?-xism: *$)
reversed: (?-imsx:^\n? *)
Upon reversing the reversed, we'd get
(?-imsx: *\n?\z)
which is proper. I've not released it yet because I've not added handlers
for ^ and $ under the /m modifier.
(?m-isx: *$) [matches "abc\ndef \nghi\n"]
reversed: (?m-isx:^ *) [matches "\nihg\n fed\ncba"]
