That is not right either, or else newbies would not be surprised by
 >>> a = [0]
 >>> b = [a]
 >>> b[0][0] = 1
 >>> a
[1]

Subscriptable collections associate subscripts with objects.
Namespaces associated names with objects.
In either case, if you change the object, you change it, regardless of 
how you access it, such as by means of other associations.
If you replace an association by associating a name or subscript with a 
new object, the old object is untouched (unless that was its last 
association) and other access methods by means of other associations are 
not affected.
