Well, there is a a subtle distinction that can be drawn: by "enumerating a 
hash", it undergoes a transformation and it isn't really a hash any more 
--order has imposed upon it, and hashes have no order. Hence David's sense of 
a "magic" to_a.  Granted this is quite minor.

So, I agree with you. I just think the word 'index' is the wrong word, and 
source of much the "confusion". If it's really needed the word 'enumerator' 
would be better.

  each_with_enumerator{|a,e| ... }

(Or perhaps just 'enum' for short)

And then each_with_index can be defined as has been suggested, per class. For 
Array it would just be an alias to the above I suppose.
