I took a quick glance at this. It hinges on how the C-API is going to
look. Currently, bytes is known in C as PyString and gets it's
representation from __str__. Although we could just change it to
__bytes__, Christian has said that he is going to rename it to PyBytes
(and what is now PyBytes -> PyByteArray). [1] Further muddying the
waters is the fact that PyObject_Str generates the unicode
representation of an object and should really be called PyObject_Unicode.
