I don't write Perl code, but its CLI has been a very good way to replace sed with something decent. sed not supoorting Perl regex syntax, the most commonly kind of regex out there by large, is frankly disappointing. Even grep was able to put it together and add the -P switch. But sed is still stuck in the prehistoric syntax of ERE ("Extended Regular Expressions", as described in man pages) which e.g. instead of \d for a digit, use [[:digit:]], a syntax present in... zero? other tools or programming environments.
