As far as fluency goes, that’s not very impressive.

    %w{Peter Julia Xi}.map{"Hello, #{it}"}.each{puts "#{it}! Enjoy your Ruby"}

That is, each language will have its strong and weak points, but so far on "fluency" I’m not aware of anything that really beat Ruby far beyond as Ruby does compared to other mainstream programming languages.

You're being way too nice. Java stream is nowhere near as easy to use as LINQ. I'd say that LINQ is easily one of the top 10 coding features that Microsoft has ever created.

You can write a vast majority of your C# codebase in a functional style if you prefer to.

All the good stuff has been pirated from F# land by now: First-class functions, pattern matching, expression-bodied members, async functional composition, records, immutable collections, optional types, etc.

This isn’t a great example of what linq is good at. There’s no reason to do ToList there, and the ForEach isn’t particularly idiomatic

Modern C# collection expressions make the definition of names closer to F#:

  string[] names = ["Peter", "Julia", "Xi"];

  var names = ["Peter", "Julia", "Xi"];

  ["Peter", "Julia", "Xi"].Select(name => $"Hello, {name}").ToList().ForEach(greeting =>   Console.WriteLine($"{greeting}! Enjoy your C#"));

I love LINQ, maybe a little too much. I can end up writing monster oneliners to manipulate data in just the right way. I love list comprehensions in python too, since they can work in similar ways

That could be shortened to

names.ForEach(name=>Console.WriteLine($"Hello, {name}! Enjoy your C#"));

For reference, Rust provides a similar experience

    let names = ["Peter", "Julia", "Xi"];
    names
        .map(|name| format!("Hello, {name}"))
        .iter()
        .for_each(|greeting| println!("{greeting}! Enjoy your Rust"));

Thank you, for someone interested in using F#, that is great.

I see you use Giraffe but I wonder how hard would it be to use Web API or to mix F# projects with C# projects in the same solution.

I know Raku from Perl fame, and F# because it’s Microsoft, but CHILL and Clipper are totally new to me, so in my own humble experience these two latter look far more obscure. :D

I'm pretty sure that there's more production code written in F# than in all those other three combined.

If we consider number of jobs, it's probably on par with Rust.
