* 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 }
*
* puts copy # => { "numbers" => [10, 20] }
* puts original # => { "numbers" => [10, 20] }
