It is not useless to identify your fundamental definitions and axioms
instead of resorting to circular reasoning.

The original question was how a beginning programmer could "get" lists.
We very quickly descended into the murky waters of "objects" of an
underlying machine and CPython's way of implementing things. I was
wondering if there was a way to "get" integers, lists, references etc
without hauling the poor student under the keel.

In a word, could Python be your first programming language?
