Breaks Hash#dig #3

Open

The extension of Hash#dig isn't compatible with the core method and can cause some horrible stuff to happen. E.g.

>> g = { foo: [10, 11, 12] }
=> {:foo=>[10, 11, 12]}
>> g.dig(:foo, 1)
=> 11
>> class Hash
>>   def dig(*path)
>>     path.inject(self) do |location, key|
?>       location.respond_to?(:keys) ? location[key] : nil
>>     end
>>   end
>> end
=> :dig
>> g = { foo: [10, 11, 12] }
=> {:foo=>[10, 11, 12]}
>> g.dig(:foo, 1)
=> nil
