No one is saying that every instance of "foo([arg])" in the docs means that the given argument is named such that it is available for keyword arguments. What people are saying is that for bool(), *that happens to be the case*. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco
