You got your chocolate in my peanutbutter!

An "id()" comparison would be, "id(this) == id(that)".  In most (all?) 
implementations, 'id()' returns the memory location, but this is an 
implementation detail that is not guaranteed and shouldn't be depended on.  
An object's python id is to be treated as an opaque identifier.
