Title
Body
If I have arr = [1, 2, 3, 4] I know I can do the following... > arr.each_slice(2) { |a, b| puts "#{a}, #{b}" } 1, 2 3, 4 ...And... > arr.each_with_index { |x, i| puts "#{i} - #{x}" } 0 - 1 1 - 2 2 - 3 3 - 4 ...But is there a built in way to do this? > arr.each_slice_with_index(2) { |i, a, b| puts "#{i} - #{a}, #{b}" } 0 - 1, 2 2 - 3, 4 I know I can built my own and stick it into the array method. Just looking to see if there is a built in function to do this.
