- to use already a few c14 convenience details : -> polymorphic std::plus, e.g. boost::mpi::reduce (world, A,C, std::c14::plus<>(),0); this plus determine the type by itself ... -> errors on the type can be very cryptic on the gf. -> add std::c14::make_unique (equivalent of make_shared for unique_ptr).
