[Python-3000] Generic functions vs. OO (original) (raw)

I've updated the page to reflect more of Jim Jewett's comments. And to reflect more of the underlying "special methods". "Container", for instance, now has "get" (for getattr), as well as "len" (for len).

By the way, all these interfaces are already in Python; they just aren't written down anywhere in a group. Instead, they are mostly scattered through the documentation, some in the Library Reference manual, others in the Language Ref manual.

(Yes, I have split the file I/O functionality into a number of separate interfaces.)

I think it would, but I don't know if we're going to get anywhere without getting more concrete. Let's tap "the wisdom of crowds". I've set up a Wiki page at http://wiki.python.org/moin/AbstractBaseClasses, and spent a little time defining some ABCs and concrete classes. I'll work on it more over the week, but feel free to pitch in and expand it. Or create alternative versions (create a new Wiki page, and put a link to it at the top of the existing page). Bill
