Call it "wsgi.url_args", and make it a two-item tuple: *args, **kw.  That's 
far simpler than any of the wacky encodings proposed so far, and can be 
used to invoke a function directly, e.g.:

     apply(f, *environ['wsgi.url_args'])

or, less cleverly (i.e. more readably):

     args, kw = environ['wsgi.url_args']
     f(*args, **kw)
