I don't find your first two points convincing. The structure of the data put in the buffer is equivalent to the interface of the function. The buffer does encourage you to use data instead of classes. I want more guidance to my users about the contract that they're expected to fulfill and I don't think buffers help with that problem. I do appreciate the temporal aspect you're talking about. I'd be all about if I was Erlang, but I don't think it's worth it for my purpose in Python.
