[boost] mpl::is_sequence< incomplete_type >?

Hi there

I tried to use mpl::is_sequence<> on an incomplete type and ran into errors
suggesting that the argument must not be incomplete (I'm using MSVC 7.0). I
assume this cannot be fixed, right?

Thanks,

Andreas

P.S. I'm compiling code similar to the following:

template< class InnerInitial >
struct build_inner_initial_list : public mpl::apply_if<
  mpl::is_sequence< InnerInitial >,
  mpl::identity< InnerInitial >,
  mpl::identity< mpl::list< InnerInitial > > > {};

class X;

int main()
{
  typedef build_inner_initial_list< X >::type whatever;
}
