What do you mean by "super instance"?  Ruby is not C++ - you cannot (and 
need not) cast a reference to another type simply because references are 
typeless.

If you just want to call the implementation of a method in the super class, 
simply use super:

class Base
  def foo() puts "base" end
end

class Derived < Base
  def foo() super; puts "derived" end
end

>> Derived.new.foo
base
derived
=> nil
>>

Kind regards
