Well, not quite. The idea that the manual is trying to express is that both
forms, "x += y" and "x = x + y" should result in final values of "x" that are
the equal to each other. The only difference should be that the *identities* of
the objects finally referenced by "x" might be different.

that is made terrible by our own mad attempt to interpret it as though it had
an underlying truth."
