a pig wearing a wig is humor
a wig wearing a pig is heresy
pigwig is a python 3 WSGI framework
(blogwig is a sample app. don't put wigs on blogs)

1. tornado-style class-based views are better
   we think you're wrong (inheritance is a hammer and this problem is no nail), but it's easy enough to achieve:

   def routes():
   	views = [
   		('/', RootHandler),
   	]
   	handlers = []
   	for route, view in views:
   		for verb in ['get', 'post']:
   			if hasattr(view, verb):
   				handlers.append((verb.upper(), route, cbv_handler(view, verb)))
   	return handlers
   
   def cbv_handler(cbv, verb):
   	def handler(request):
   		return getattr(cbv(request), verb)()
   	return handler
   
   class RootHandler:
   	def __init__(self, request):
   		self.request = request
   
   	def get(self):
   		return Response('hello')

2. flask-style decorator-based routing is better
   we think you're wrong (explicit is better than implicit), but it's easy enough to achieve:

   routes = []
   def route(path, method='GET'):
   	def wrapper(handler):
   		routes.append((method, path, handler))
   		return handler
   	return wrapper
   
   @route('/')
   def root(request):
   	return Response('hello')

3. django-style integration with an ORM is better
   you're wrong
