Reminds me of spreadsheet-fortran ( https://github.com/lwsinclair/spreadsheet-fortran ), a project creating a VisiCalc lookalike in FORTRAN 66, which even runs on a PDP-11.

I can see the subtle distinction you make. The flang notes on array composition provide a good introduction to the way array expressions ( https://flang.llvm.org/docs/ArrayComposition.html ) are treated. But in practice

The "!omp simd" works very well IMO. In general however, the auto-vectorizer tends to do a pretty good job.

The NumPy part is a misconception. Fortran is used in SciPy however.

Personally, I like to think of Fortran as the language of large-scale numerical PDE and eigenproblem solvers. Most scientific and engineering problems boil down to one of these two.

Bjarne Stroustrup on Fortran users [1]: > Fortran is harder to compete with. It has a dedicated following who [...] care little for programming languages or the finer points of computer science. They simply want to get their work done. [

A few of these things exist already: - http: https://github.com/fortran-lang/http-client - sockets: https://github.com/modern-fortran/tcp-client-server - threads: https://github.com&#x2

For "broadcasting" an array along a particular axis, you'll need to use the function "spread(source,dim,ncopies)". But mixed array/scalar expressions are indeed supported.

OpenMP support in Fortran will improve as flang matures. In OpenMP 5.0 "#pragma omp requires unified_shared_memory" was introduced. At LLNL, they are are currently building El Capitan ( https://www.datacenterknowledge.co

They do. Some national HPC centers offer Fortran courses including elements of Fortran 2018 [1,2], including the latest features. (Disclaimer: I work at one.) The Intel Fortran compiler already includes some Fortran 2023 features [3]. [1]

Historically, it has been easier for vendors to work in their own walled gardens, and get customers locked in, than it is to collaborate on open standards and APIs.

For fun, I wrote a CHIP8 interpreter in Fortran recently [1]. Fortran is still heavily used in computational chemistry, computational fluid dynamics, marine engineering, nuclear engineering, reservoir engineering, and numerous other enginee
