What are the advantages of Julia over Fortran?

Interop: Julia can very easily call code from python, R, C, C++, and Fortran. Fortran can’t currently call Python, R, or Julia.

I don’t see any reason Python, R, or Julia code couldn’t be used in Fortran if stdin/stdout and pipes were used on *nix systems. There are certainly efficiency concerns regarding that, which is why it isn’t likely seen in practice, when a domain expert could implement the algorithm in Fortran directly, instead of calling out to a less efficient implementation.

Is there something I’m missing or mistaken about?

In the thread Fortran calling R I showed a Fortran code writing unformatted stream data that is then processed by R, and @ivanpribec demonstrated a better approach using his Fortran-Rinside package.
