With Ruby 1.9.2-preview1, it is no longer possible to use send to call 
protected methods. It is however still possible to call private methods.

   class TestClass
     protected

     def protected_test
       puts 'called protected'
     end

     private

     def private_test
       puts 'called private'
     end
   end

   t = TestClass.new
   t.send :private_test
   t.send :protected_test

With ruby 1.9.1p243 (2009-07-16 revision 24175) [i686-linux], this gives 
the output:

   called private
   called protected

But with ruby 1.9.2dev (2009-07-18 trunk 24186) [i686-linux], an 
exception is raised calling the protected method:

   called private
   /tmp/protected.rb:17:in `<main>': protected method `protected_test' 
called for #<TestClass:0x82134c0> (NoMethodError)

Is this an intentional change for Ruby 1.9.2, or should I raise a bug?

Thanks,

Phil
