The wait attribute in xep_0045's join_muc method doesn't seem to have any effect after quickly reading the module.

If wait, then the code uses some non-existing API for XMLStream.send: self.xmpp.send(stanza, expect), expect being an ET.Element.

As far as I can see, XMLStream.send takes an ElementBase (or anything else that it will send with send_raw) and a boolean. Thus expect is most likely casted to boolean (True), and rendered useless.
