The class of A is "Class" (which is itself an object different from
A). So it's perfectly normal that the hash method returns an other
value.

Try A.object_id and A.class.object_id:

>> Array.object_id
=> 2148226700
>> Array.class
=> Class
>> Array.class.object_id
=> 2148257020
>> Class.object_id
=> 2148257020

Array.class and Class are the same object.
