 Replying to [comment:1 ramey]:
 > I don't know what you mean by a "strongly typed enum".  If you want to
 post a small sample I'll have a look at it.  But until that happens
 there's nothing I can do.

 I mean the new C++11 strongly typed enumeration as described here:[[br]]
 http://en.wikipedia.org/wiki/C%2B%2B11#Strongly_typed_enumerations


 Compiling the following gives the error:[[br]]
 C:\Boost\include\boost-1_47\boost/serialization/access.hpp(118): error :
 expression must have class type

 {{{
 enum class MyEnum { first, second, third };
 MyEnum myenum = MyEnum::second;

 std::ofstream file( _T("serialized_enum"), std::ios::out |
 std::ios::binary );
 boost::archive::binary_oarchive outArchive( file );

 outArchive << myenum;
 file.close();
 }}}
