Text::CSV is a thin wrapper for Text::CSV_XS-compatible modules now.

Of course, you are right. But one or one and a half decades ago, when I had to handle CSV files from Perl for the first time, Text::CSV was what now is Text::CSV_PP. That's written to my biological persistent storage, and it's damn hard to update. ;-) I know that, because it's not the first time that someone had to remind me.
