---------------------------------------------------+------------------------
 I'm using the indirect array proxies with
 BOOST_UBLAS_ENABLE_PROXY_SHORTCUTS defined. The template parameters of
 matrix_indirect / vector_indirect in matrix_expression / vector_expression
 are invalid.

 See lines 372-381 in expression_types.hpp  (in SVN revision 39369).
 Changing matrix_indirect<E, A > to matrix_indirect<E,indirect_array<A> >
 seems to solve the problem.

 {{{
 #define BOOST_UBLAS_ENABLE_PROXY_SHORTCUTS

 #include <vector>
 #include <boost/numeric/ublas/matrix.hpp>
 #include <boost/numeric/ublas/vector.hpp>
 #include <boost/numeric/ublas/matrix_proxy.hpp>
 #include <boost/numeric/ublas/vector_proxy.hpp>

 int main()
 {
   using namespace boost::numeric::ublas;
   indirect_array<std::vector<std::size_t> > ia;
   matrix<double> m;
   vector<double> v;
   m(ia,ia); // compilation error
   v(ia);    // compilation error
 }
 }}}
