Iterators are often nice, but are no replacement for loops. Try processing multidimensional arrays without loops.

  > iterators > without loops This is a false dichotomy. You can use iterators to replace three-clause loops without changing the body: for row in 0..rows { for col in 0..cols { arr[row][col] } } This is far easier to read than three-clause loops which repeat redundant information repeatedly and redundantly.

    OK, but you're still using loops.

      You are, but that was never in question.
