Sounds like a contradiction in terms to me: "some completely contingent 
order" != "special order"?  It's still order either way. Nonetheless, even 
though a Hash by definition has no order, I doubt anything in a computer 
system lacks for order ;)

Sorry, guess I wasn't clear enough. I didn't mean the per class methods; 
rather the common Enumerable#each_with_index method, i.e. giving it a new 
name. But David seems to like #each_with_counter anyway, which is fine with 
me.
