futzing around with changing what the inheritance of a class is. (objects made with the old class will still use the old class' inheritance, though)

ruby class munging.rb

bash>> irb
class A;>> class A; end
=> nil
>> class B; end
=> nil
>> the_class = A
=> A
>> class C < the_class
>>   end
=> nil
>> C.ancestors
=> [C, A, Object, Kernel, BasicObject]
>> the_class = B
=> B
>> class C < the_class
>>   end
TypeError: superclass mismatch for class C

>> C = Class.new(the_class)
