I tried the above sample code in 2.1.2 and the error has changed from a TypeError to a NoMethodError: "NoMethodError: super: no superclass method `hello' for #<O:0x007fb799046c50>"
Is that the fix?
From my perspective it would be not a fix but a refusal to implement using super when binding an UnboundMethod to an object. Have I misunderstood something?

Feature #8546: super errors in UnboundMethods

`UnboundMethod`s are unable to call `super`

~~~ruby
module M
  def hello
    puts "hello from M"
  end
end

class O
  def hello
    puts "hello"
  end
end

o = O.new
o.hello #=> "hello"
M.instance_method(:hello).bind(o).call #=> "hello from M"

module M
  def hello
    super
  end
end

M.instance_method(:hello).bind(o).call #=> TypeError: self has wrong type to call super in this context: O (expected M)}))
~~~

Given that the non-super method works, I would expect super to work.
