+class Array
+  # Converts the array to a comma-separated sentence where the last element is
+  # joined by the connector word.
+  #
+  # You can pass the following kwargs to change the default behavior:
+  #
+  # * <tt>:words_connector</tt> - The sign or word used to join all but the last
+  #   element in arrays with three or more elements (default: ", ").
+  # * <tt>:last_word_connector</tt> - The sign or word used to join the last element
+  #   in arrays with three or more elements (default: ", and ").
+  # * <tt>:two_words_connector</tt> - The sign or word used to join the elements
+  #   in arrays with two elements (default: " and ").
+  #
+  # ==== Examples
