ECMWF tries to move to a programming paradigm where at least the outer
structure of the model(s) use object oriented design (the reason for
this is complicated, but it stems from the fact that they noticed they
copied -and then slightly modified- far too much code).
Obviously, it would be easiest if they could use Fortran for this -
their "toy model" code at the moment has both a C++ variant and a
Although I haven't looked into it yet, my impression is that the Fortran
variant is rather crippled by the fact that they want to (also) compile
it with Gfortran (See http://gcc.gnu.org/wiki/Fortran2003Status) for
where Gfortran is, 2003-wise.
