My thoughts about fortran oscillate as well. If I have the option, I try to just use Python + Cython. But if I had to choose between C/C++ and fortran for *numeric* projects, I would probably choose fortran these days, + fwrap or f2py + Python. Especially after reading benchmarks like these: http://www.oonumerics.org/blitz/benchmarks/acou3d.html where one needs to use templates and lots of expertize in C++ to even beat fortran code written by pretty much anybody...
