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 ?
