Subject: process two arrays pairwise?

Is there somewhere in Ruby a way to process the elements of two arrays (of equal
size), pairwise?

I'd like something better than this, if there is something:

  array1.each_with_index { | a1, i |
    a2 = array2[i]
    # process a1, a2
  }

preferably something that doesn't mind if the collections aren't indexable?

Thanks,

I'm giving the best advice I have. You get to decide whether it's true for you.
