- *  Note that this method creates a shallow copy of the value in _other_hash_.
- *  This means that when for example Array#select! is used on one of the values
- *  in _other_hash_ both the original object as well as the copy will be
- *  modified. This is illustrated in the following example:
- *
- *    original = { "numbers" => [10, 20, 30] }
- *    copy     = {}.merge(original)

- *    copy["numbers"].select! { |number| number <= 20 }
