There is another problem. If C2 doesn't inherit another class but does
include the modules and those modules by themselves include modules
then your code, still, will return the whole hierarchy. Look at this:

module M1; end
module M2; include M1; end
class C2; include M2; end

p (C2.ancestors - [C2] - C2.superclass.ancestors) # => [M1, M2]

That's because C2.superclass => Object
