Just because two instances from the same object have the same value does not

I think they *are* equal in Python if they have the same value, by definition,
because somewhere the Python docs state
that equality compares the object's values.
And is personality of no value, then?
The reality though is that value is more vague than equality test (as it was
already pointed out in this thread): A
class designer can directly implement what equality means to the class, but he
or she cannot implement an accessor
method for the value. The value plays a role only indirectly as part of
equality and ordering tests.
Not sure what you mean by this.
