Comment (by Alain Miniussi <alain.miniussi@…>):

 Another issue with th e implicit solution is that the input buffer is not
 left unchanged, while it is documented as such. So I guess a acceptable
 solution would be to simply provide a global:
 {{{
 namespace boost{ namespace mpi {
 template<typename T> T const* mpi_in_place(T const* p = 0) { return
 static_cast<T const*>(MPI_IN_PLACE); }
 } }
 }}}

 function ?
