Guan,
HashWithIndifferentAccess is just like any other hash except that the
key 'somekey' will be the same as the key :somekey.
For example if you have a regular hash like the following
>> hash = Hash.new({:somekey => 'testing'})
>> hash[:somekey]
=> testing
>> hash['somekey']
=> nil
Notice how the key 'somekey' is not the same as the key :somekey
>> hash = HashWithIndifferentAccess.new({:somekey => 'testing'})
>> hash[:somekey]
=> 'testing'
>> hash['somekey']
=> 'testing'
Here the key 'somekey' and :somekey are the same.
Understand?
