Comment (by anonymous):

 I would really sorry for the confusion caused by my comments  2,3. I
 coudn't find any way to delete comments.

 But we should bring the original issue. The original one is that "boost
 binary archive does not consider of sized-enums. It treats all the enums
 as int-sized" as described in comment 4.

 So it causes some problems:
 {{{
 // from iserializer.hpp, load_enum_type<>::invoke<>(...):
 int i;
 ar >> boost::serialization::make_nvp(NULL, i); // loads as "int"
 t = static_cast< T >(i); // convert it to "enum type"
 }}}
 When T is such
 {{{
 enum class PacketCode : unsigned char
 {
         Something,
 };
 }}}

 Again, I sorry for bothering you.
