# 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). These
# classes are *not* APIs. None of these classes, nor the
# ``HTTP_METHOD_FACTORIES`` lookup dict should be imported directly by
# user code.
