I'd personally be in favour of the notion of also allowing strings as the first argument, so you could instead write:

You had me until here...
(Independent of this idea, it would actually be nice if the operator module had a dictionary mapping from op symbols to names, like operator.by_symbol["+="] giving operator.iadd)

+1 from me as well. The table already exists in the docs ( http://docs.python.org/3.4/library/operator.html#module-operator), it just needs to be codified. Maybe operator.map['+='] or operator.from_syntax['+=']. Go really nuts and support ['.attribute'] or [''] to auto-generate attrgetter or itemgetter instances, but that's probably just asking for support problems.
