If you meant "he value of a *variable* is a pointer to an object, not the 
object itself", then bingo, yes, that's what it's like in my world.

The explanation makes perfect sense - i think the names-values-bindings 
terminology is consistent, correct and clear. It's just that i think that 
the variables-objects-pointers terminology is equally so, so i object to 
statements like "python is not pass-by-value".
