bind(p1) public

Bind umeth to obj. If Klass was the class from which umeth was obtained, obj.kind_of?(Klass) must be true.

   class A
     def test
       puts "In test, class = #{self.class}"
     end
   end
   class B < A
   end
   class C < B
   end

   um = B.instance_method(:test)
   bm = um.bind(C.new)
   bm.call
   bm = um.bind(B.new)
   bm.call
   bm = um.bind(A.new)
   bm.call

produces:

   In test, class = C
   In test, class = B
   prog.rb:16:in `bind': bind argument must be an instance of B (TypeError)
