events() generator is generating str, not dict

[bo0ts]

I was baffled by the following (on Python 2.7):

for ev in client.events():
    assert isinstance(ev, str), 'ev is not a string' # Does not trigger
    assert isinstance(ev, dict), 'ev is not a dict' # Does trigger

Is that as intended or am I right in assuming that this should actually be a dict?

for ev in client.events(decode=True):
    assert isinstance(ev, dict)

Needs to be documented :)
