At the time of this writing, falcon.testing.Result has no custom __repr__:

>>> import falcon
>>> import falcon.testing
>>> app = falcon.App()
>>> client = falcon.testing.TestClient(app)
>>> result = client.get('/something')
>>> result
<falcon.testing.client.Result object at 0x7f292ce046d0>

The docs do not give a format option for iso date with microseconds. Is this possible?
