What is the proper way to handle this? Below is my structure:
template< typename t_type >
struct is_sink
{
    typedef typename boost::mpl::or_<
        vfx::io::is_device,
        boost::is_same
    > type;
^
missing "::type" here? Otherwise, the "typename" above is probably illegal
typename is legal because the or_ is qualified.  It doesn't matter
that boost::mpl is a namespace.  (Don't you just love these intuitive rules)
