  ["1", "2", "3", "4"]
  ["5", "6", "7", nil]
  ["8", "9", "10", nil]

  %w(1 2 3 4 5 6 7).in_groups(3, ' ') {|group| p group}
  ["1", "2", "3"]
  ["4", "5", " "]
  ["6", "7", " "]

  %w(1 2 3 4 5 6 7).in_groups(3, false) {|group| p group}
  ["1", "2", "3"]
  ["4", "5"]

Splits or iterates over the array in groups of size number, padding any remaining slots with fill_with unless it is false.

  ["1", "2", "3"]
  ["4", "5", "6"]
  ["7", nil, nil]

  %w(1 2 3).in_groups_of(2, ' ') {|group| p group}
  ["1", "2"]
  ["3", " "]

  %w(1 2 3).in_groups_of(2, false) {|group| p group}
  ["1", "2"]
  ["3"]

Divides the array into one or more subarrays based on a delimiting value or the result of an optional block.

  [1, 2, 3, 4, 5].split(3)                # => [[1, 2], [4, 5]]
  (1..10).to_a.split { |i| i % 3 == 0 }   # => [[1, 2], [4, 5], [7, 8], [10]]
