Actually it's not. It's an AssociationProxy object pretending to be an

 At this time, when

     s.votes.create

 is called, it actually invokes a method of the Vote class?  How come an
 Array class object can invoke a Vote class method?

not like this?

irb(main):010:0 class Foo
irb(main):011:1   def class
irb(main):012:2 return Fixnum
irb(main):013:2   end
irb(main):014:1 end
= nil

irb(main):015:0 f = Foo.new
= #Foo:0x4799ce8

irb(main):016:0 f.class
= Fixnum

irb(main):017:0
