Multiplexing multiple .observe() onto the same Watcher?

[radoye]

The code

I'm using a slightly modified sum_lazy.py

# create watcher object as usual
w = tw.Watcher()

weights = None
for i in range(10000):
    weights = [random.random() for _ in range(5)]

    # let watcher observe variables we have
    # this has almost no performance cost
    w.observe(weights=weights, pqr=42)
    w.observe(my_test=[-x for x in weights])
    w.observe(**{"my_testX": [-x for x in weights]})
    time.sleep(1)

and a slightly modified lazy_logging.ipynb

client = tw.WatcherClient()
#stream = client.create_stream(expr='lambda d: np.sum(d.my_test)')
stream = client.create_stream(expr='lambda d: print(d)')

Expected behavior

I'd like (expect?) different observations to be multiplexed into the stream.

Observed behavior

Only the first call to .observe() produces an event.
