QOTW: "*what* the value is is defined by the operations that the object
supports (via its type).
*how* the value is represented inside the object is completely
irrelevant; a Python implementation may use electric charges in small
capacitors, piles of rocks, diapers,or an endless supply of small guys
in odd costumes to encode the value inside an object. Changes to the
value may be carried out by CPU instructions, caterpillars, toddlers
with gasmasks, or an endless supply of small guys in odd costumes. The
only thing that's important is that you can, in your Python program,
access an objects value via its type, and get other objects back when
you do." - Fredrik Lundh
