Ruby `each_with_object` with index

Question

I would like to do a.each_with_object with index, in a better way than this:

a = %w[a b c]
a.each.with_index.each_with_object({}) { |ar         


        

Answer 1

You could replace your last line with

puts "i is: %d, v is %s" % arr.reverse

but, as @sawa suggested, disambiguating the array's argument is the thing to do here. I just mention this as something to be stored away for another day.
