I think that's an absolutely fantastic idea. Request / Response objects
are the one thing that almost all Python web frameworks deal with in
some way, and a standardised interface for them in the standard library
could do a lot for improving cross-framework compatibility.

I have plenty of enthusiasm, but it's coupled with youthful ignorance
(I've been using Python for web development for just over a month). That
said, I'm happy to contribute serious time and effort to this.
In a previous post I outlined the things that I liked about PHP's web
interface features, which while not exactly modelled on a
request/response object do cover the same ground. I think the most
valuable thing PHP's treatment of this brings to the table is the
concept of GET, POST and COOKIE dictionaries for looking up data sent by
the client (also the REQUEST dictionary which combines the three).
One other thing I've been thinking about recently is that HTTP requests
and HTTP responses both consist of a set of headers and a body, in a
very similar way to MIME email messages which are already well catered
for by the standard library. I think any standard for request/response
objects should aim to closely match the way MIME style messages are
handled by other parts of the standard library (in particular the email
