Good catch! Fixed in svn. The latter paragraph now reads: """ Like the bytes type in Python 3.0a1, and unlike the relationship between str and unicode in Python 2.x, attempts to mix bytes (or buffer) objects and str objects without specifying an encoding will raise a TypeError exception. (However, comparing bytes/buffer and str objects for equality will simply return False; see the section on Comparisons above.)
