ruby - Why does `BasicObject` answer methods `superclass` and `class`? -

if object < basicobject, , #superclass , #class defined in object, how possible class < basicobject answers a.superclass , a.class? a.ancestors: [a, basicobject]

going further (according new answers):

if a instance of object why doesn't have in ancestors?

class b;end b.ancestors # => [b, object, kernel, basicobject] 

superclass might defined in kernel, a doesn't have kernel in ancestors.

kernel included in object (from object.rb):

class object < basicobject   include kernel end 

p.s git issue confused me enough ask it

class < basicobject end 

here, class a instance of class class.

a.class #=> class 

a answers .class , .superclass because class supports them.

what thinking instance of a, in case:

a.new (object doesn't support #inspect) =>
