# We use 'precooked' Request subclasses that correspond to HTTP

# request methods within ``router.py`` when constructing a request
# object rather than using ``alsoProvides`` to attach the proper
# interface to an unsubclassed webob.Request.  This pattern is purely
# an optimization (e.g. preventing calls to ``alsoProvides`` means the
# difference between 590 r/s and 690 r/s on a MacBook 2GHz).
