I've updated the page to answer a few questions Jim Jewett posed, and to expand a few more interfaces. I haven't tried to explain the implementation types, like Code or Frame. I'm hoping someone else will do that. I've broken up the File type into a set of types which attempt to capture (1) the difference between an open file-system file, and a file-like object, and (2) the difference between files opened in binary mode and files opened in text mode.
Going through the type system again is interesting, and raises a few questions about some of the interfaces. For instance, should files opened in binary mode support iteration? If so, what's the unit of iteration? See http://wiki.python.org/moin/AbstractBaseClasses for more.
