[Web-SIG] wsgi.url_vars feedback

[Luke Arno]

I feel even more +1 on ['wsgi.url_vars'] now. I implemented
as currently discussed in selector and it works out very well.

Selector now supports positional args in path expressions.
I even made some experimental little decorators so that
url_vars can go into method signatures. I don't know that
I will ever use them (bit clever). Info is on the selector
page (badly in need of work though it may be):

(Selector is now LGPL by popular demand, BTW.)

Cheers,
