The following works:

   < unsigned I
struct a

struct f4
     template< typename T1, typename T2, typename T3, typename T4 >
     struct apply
         typedef vector<T1,T2,T3,T4> type;

MPL_TEST_CASE() // partially bound metafunction classes
     typedef bind4<f4, a<1>,a<2>,_1,_2 > f4_a1_a2;
     typedef apply_wrap2<f4_a1_a2, a<3>,a<4> >::type f4_a1_a2_a3_a4;
boost::is_same<f4_a1_a2_a3_a4,vector<a<1>,a<2>,a<3>,a<4> > > ));

So, apparently, the n in apply_wrapn is >= max placeholder arg
in the bind args. Rereading boost.bind, I now see the
similarity. Sorry for the noise, but further examples
like the f4 example above would have helped.
