 /**
  * This function can be thought of as a hybrid between PHP's array_merge and array_merge_recursive. The difference
  * to the two is that if an array key contains another array then the function behaves recursive (unlike array_merge)
  * but does not do if for keys containing strings (unlike array_merge_recursive). See the unit test for more information.
  *
  * Note: This function will work with an unlimited amount of arguments and typecasts non-array parameters into arrays.

  * @param array $arr2 Array to merge with
