I started using F# late last year in a *nix environment and it is really well done. There's .NET Interactive which allows for F# in a Jupyter Notebook. You can create .fsx scripts that are interpreted at runtime and handle inline dependencies from NuGet. There's the Fable which compiles F# to JS, TS, Python and Rust.

And of course it's a full on functional language with some great syntactic sugar, especially computation expressions.

The stomaching of .NET basically means getting a much larger set of third-party libraries than OCaml or Haskell can offer.

It is well worth checking out!

The part about C++ is true, when you need to use a combination of SIMD/CUDA/MPI there is no game in town but C++. The ecosystem is so vast, we rely on too many scientific/numerical libraries that took tiny armies of grad students to create.

But for new projects in the future, I am looking towards Mojo and Chapel.

You mean...not suffering through cmake and co and having your project build the first time you type dotnet build -c Release?

(I suppose a valid excuse for suffering from C++ tooling would be getting to use something like ISPC)
