Anarki has a lot of great stuff in it, but it also has alot of crap in it. I spent 2 weeks just going through the code pulling out the pieces I like from Anarki and not the rest. I certainly hope pg keeps the arc code down to the dozen or so core files forcing the community to build libraries on top rather than integrate adhoc extras at such a low level that it's brutal to separate the good from the bad.
