Uhm... don't know about MPL, but isn't this a good example for
type_traits? Something like:
template <class T>
bool SetOption(COptionInfo& o, const char* key, const T& value)
{
BOOST_STATIC_ASSERT( boost::is_same< T, bool >::value ||
boost::is_same< T, int >::value ||
boost::is_same< T, double >::value ||
boost::is_same< T, std::string >::value );
...etc...
}
Regards, Daniel
