Those are invariants, not a definition. The actual definition is found in the paragraph above: "In most Scheme systems, two objects are considered identical if they are represented internally by the same pointer value and distinct (not identical) if they are represented internally by different pointer values, although other criteria, such as time-stamping, are possible." In other words, object identity in Scheme is also established by an integer that may or may not correspond to a memory address. How is this any different from Python's definition? -- https://mail.python.org/mailman/listinfo/python-list
