Getting closer:

def from_path(*keys):
    def decorator(http_handler):
        def handler_wrapper(*args, **kwargs):
            kwargs = dict(zip(keys,args))
            return http_handler(args[0], **kwargs) 
        return handler_wrapper
    return decorator

class HelloWorld(object):
    def _cp_dispatch(self, vpath):
        print("dispatching " + repr(vpath))
        return self.index
    
    @cherrypy.expose('/')
    @from_path('one','two','three')
    def index(self, **kwargs):
        return f"My kwargs were {kwargs}"
    
cherrypy.quickstart(HelloWorld())

If I GET /a/b/c, the server responds with:
My kwargs were {'one': <__main__.HelloWorld object at 0x7f45622dd860>, 
'two': 'b', 'three': 'c'}

I am unsure what's eating the first path segment there.

I would like to implement something similar to the way ASP.NET does 
attribute-based routing but I'm not sure how much further I'll get. It's 
been an interesting dive into CherryPy at the least.
