Oh, sorry, I should have specified: I used Anarki-specific stuff in several places. Mostly the date-manipulation, but also ssplit (I actually hadn't realized that wasn't in arc2. Yikes). Using Anarki, it should work, though.
I totally agree that strings ops are important. If I recall, PG has also said something to this effect, so I wouldn't be surprised if more of them crop up in the next few releases.
