As you can see, the parameter name is 'x'.
OK, your response is clarifying my point ;)
I didn't realize that in the bool([x]) syntax, identifier x refers to a
"genuine" argument [I was considering x as referring to a "generic" object
having a boolean value].
Nevertheless, compare with the definition the doc provides for the builtin
function dir():
dir([object])
[definition omited, just observe the declaration syntax]
Now, lets make a try
>>> dir(object="Explicit is better than implicit")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: dir() takes no keyword arguments
>>>
Not very meaningful, isn't it ?
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*.
