Technically, but what is the point? You can't do pointer-style things
with it. You can't change the object in any way without changing the
id, and you can't use the mechanism to, for instance, allow 'var'
In short, you are showing evidence of the use of pointers internally
within Python, but that is not the same as providing pointer-like
