Hopefully, the SciPy community can stay open-minded about modern Fortran libraries. Modern Fortran is quite different from Fortran 77, while being as powerful, if not more. In addition, there has been a significant community effort on improving and modernising the legacy packages, the ecosystem, and the language itself. With projects like LFortran (https://lfortran.org/), fpm (https://github.com/fortran-lang/fpm), and stdlib (https://github.com/fortran-lang/stdlib), I believe that Fortran will enjoy prosperity again.

I also like FPM and the ecosystem. In case anyone is just getting started with Fortran, definitely checkout the Fortran Standard Library project: https://github.com/fortran-lang/stdlib

If you need to clear memory in the local scope, you need to deallocate a variable explicitly. Otherwise, all Fortran variables are cleared automatically when they go out of scope. One exception are Fortran pointers (different from C pointers) which are discouraged unless really necessary. We have a discussion for a high-level wrapper for files here: https://github.com/fortran-lang/stdlib/issues/14. So, it's in scope we just haven't gotten far with the design and implementation.

Some projects of the Fortran-lang community are Fortran Discourse, https://fortran-lang.discourse.group/, a web site, https://fortran-lang.org/, stdlib, https://github.com/fortran-lang/stdlib, a standard library for Fortran, and LFortran https://lfortran.org/, an interactive LLVM-based Fortran compiler under development.
