I used Fortran 2008 a lot some years ago; initially I wanted to write a C++ wrapper around a Fortran library that seemed useful, but ended up liking the language better than C++ and just did the whole project in it. I think a lot of people don’t realize that modern Fortran actually supports object-oriented programming and Matlab-style array slicing, and comes with built-in support for e.g. matrices and complex numbers. It even has some features inspired by functional languages, like being able to mark functions as pure (side-effect free). Combined with its general speed, this makes it a pretty nice language for numerical code. Although for most new users, I think Julia might be a better option than Fortran these days.
