Subject: [1.9] nil.instance_eval


 Sorry, there is something that I've not understood in bootstraptest/test_eval.rb  

assert_equal 'ok', %q{
  begin
    nil.instance_eval {
      def a() :a end
    }
  rescue => TypeError
    :ok
  end
}, '[ruby-core:16796]'

assert_equal 'ok', %q{
  begin
    nil.instance_exec {
      def a() :a end
    }
  rescue => TypeError
    :ok
  end
}, '[ruby-core:16796]'


 If I can write this

vgs% ./ruby -ve 'def nil.a() :a end'
ruby 1.9.0 (2008-05-20 revision 16491) [i686-linux]
vgs% 

 why I can't use instance_{eval,exec} to define method with nil ?
