Sorry, the body for this function should of course be as follows.
(I edited some of the code to remove some cruft from our current version)

std::ostream & EnumIOBase::out(std::ostream & os, int value) const
{
     MapOut::const_iterator i = m_i->m_mapOut.find(value);

     if (i != m_i->m_mapOut.end()) {
         os << i->second;
     } else {
         os.setstate(std::ios::failbit);
     }

     return os;
}

Cheers,
