There are dozens of little cleanups and improvements right and left throughout this series, so I urge you to take a look at the whole thing. I've tried to take into consideration lots of concerns and suggestions from many of you over the last week. There is also now documentation! And the test suite now has full coverage of all functions. Finally, there's been some significant benchmarking, and now a few commit messages have some performance numbers. Please send your Reviewed-by lines as you see fit. Regards, Jason Jason A.
