Ruby

Given the following t.rb:

module A def foo puts "A#foo" super end end class B def foo puts "B#foo" end end class C < B include A def foo puts "C#foo" super end end module D refine A do def foo end end end C.new.foo 

Even if D is not used, B#foo cannot be called by super in A#foo:

$ ruby t.rb C#foo A#foo Traceback (most recent call last): 2: from t.rb:30:in `<main>' 1: from t.rb:19:in `foo' t.rb:4:in `foo': super: no superclass method `foo' for #<C:0x00005623950b74f8> (NoMethodError)
