    Ah, thank you.  I would never have guessed that I _was_ looking too 
hard...
    ...but now I have another question!  I wanted to include Enumerable so I 
could do something like this:


%w(a b c d).each_with_index do |obj, i|
    if some_other_array[i] == obj
        # do something
    end
end


    So, just to make sure I understood what I was doing, I removed the 
"include Enumerable" line of my code and... it all still worked.  Now, 
what's up with that?  Array has an "each_with_index" already?  Does it 
already include Enumerable?
    Thank you for the clarification!  I always like to understand what's 
going on...
