Yeah, I agree with the broader claim. IMO well-structured Haskell will tend to be easier to maintain then well-structured Perl, and poorly structured Haskell will tend to be easier to get well structured than poorly structured Perl.
I just thought the express claim being made significantly oversold it. Whichever approach you take with the Haskell in the example under discussion, modifying the Haskell is not easier than adding a handful of characters to a simple regex.
