I'm not the author, but I don't think this amazing little library has gotten the attention it deserves. I saw that the author Sébastien Loisel submitted it to HN about a year ago when he first made it, but it wasn't picked up. So I'm re-submitting. Any detailed questions about the implementation will need to be directed to the author.
