- Previously, ``pyramid.request.Request`` inherited from

  ``webob.request.Request`` and implemented ``__getattr__``, ``__setattr__``
  and ``__delattr__`` itself in order to overidde "adhoc attr" WebOb behavior
  where attributes of the request are stored in the environ.  Now,
  ``pyramid.request.Request`` object inherits from (the more recent)
  ``webob.request.BaseRequest`` instead of ``webob.request.Request``, which
  provides the same behavior.  ``pyramid.request.Request`` no longer
  implements its own ``__getattr__``, ``__setattr__`` or ``__delattr__`` as a
  result.
