Thanks for posting. It's been excruciatingly hard to find anyone
besides Phillip interested in GFs or able to provide use cases. For me
they're mostly still something theoretically interesting from other
languages, like continuations. Maybe you can round up some more users?

FWIW, I think the Turbogears use you're thinking of is jsonify, a GF
for converting arbitrary Python data into JSON (JavaScript Object
Notation). But I'm not aware of it using any of the advanced features
-- it seems to be using just the basic facility of overloading on a
single argument type, which could be done with my own "overloading"
example (see the Python subversion sandbox). At least that's what I
got from skimming the docs:
http://docs.turbogears.org/1.0/JsonifyDecorator . That article claims
that TurboGears uses RuleDispatch extensively. I'd love to hear from
them about how they use the advanced features.
