Ruby consume array part by part

Question

Hi,

Let's say I've array with n elements. I want to take first ten elements and do something with them and then next ten and so on until array is done.

What's the right Ruby way to do it? (With c-language background I could write some for-loop and inside the loop count to ten, do stuff and set my bookkeeping variable to zero and continue main array handling..)

#!/usr/bin/ruby1.8

a = (1..10).to_a
a.each_slice(3) do |slice|
  p slice    # => [1, 2, 3]
             # => [4, 5, 6]
             # => [7, 8, 9]
             # => [10]
end
