I was in my second class of the Python workshop I'm giving here in one
Argentine University, and I was explaining how to think using
name/object and not variable/value.

Using id() for being pedagogic about the objects, the kids saw that
id(3) was always the same, but id([]) not. I explained to them that
Python, in some circumstances, caches the object, and I kept them
happy enough.

But I really don't know what objects and in which circumstances.
