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 
Fortran variant.

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.
