Really good examples of exposing class decorators. Taken from bottle.py Nothing here makes sense it is just for me to remember how to write some code.

examples.py

+get    = functools.wraps(Bottle.get)(lambda *a, **ka: app().get(*a, **ka))

+put    = functools.wraps(Bottle.put)(lambda *a, **ka: app().put(*a, **ka))
+delete = functools.wraps(Bottle.delete)(lambda *a, **ka: app().delete(*a, **ka))
+error  = functools.wraps(Bottle.error)(lambda code: app().error(code))
