Not good, because then the same value in different fields has identical influence on the hash code.

Better because that considers position. But still, I don't see the need. Note also that a proper Hash key usually should be immutable because changing them causes all sorts of trouble if not done carefully. And most of the time Hash keys are String, Symbol, Fixnum and the like - which all do have their #hash implementation already.
