Im not sure what more to say at this point. If i fix this ill give a pull request, but I only just found this library so not sure if ill be able to work it out before you could, or if Im even using this library right.

P.S. @bruth also, this little library is the exact kind of thing I wish there was more of in python. :) 👍
