 Test Script:
 {{{
 #!ruby
 def test(&block)
   begin
     block.call
   rescue ArgumentError
     puts " - OK"
   else
     puts " - NG"
   end
 end

 str = "xyz"
 enum = str.enum_for(:each_byte)

 puts :each
 test{ enum.each(123) }

 puts :each_with_index
 test{ enum.each_with_index(123) }
 }}}

 Result:
 {{{
 $ macruby t.rb
 each
  - OK
 each_with_index
  - NG
 }}}

 Enumerator#each and #each_with_index are written to reject an argument.
 {{{
     rb_objc_define_method(rb_cEnumerator, "each", enumerator_each, 0);
     rb_objc_define_method(rb_cEnumerator, "each_with_index",
 enumerator_each_with_index, 0);
 }}}
