Of the "*rv" expression.
I'm confused. You're saying *rv is equivalent to rv ??
Ok, let me try again: if iterator is also a model of the readable iterator concept, then expression *rv should be equal to *v, where v is the value of iterator before call to operator++(int) and rv is the value returned from the call. The good question is what 'equal' means? Operator== might not be defined. The standard uses 'equivalent' but I don't know what that means. - Volodya
