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

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

That’s of course trivial examples. And while Ruby now have RBS and Sorbet, it’s yet another tradeoff compared to a syntax that has upfront static analysis as first class citizen in mind.

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.

Ruby is dynamically typed, which makes "fluent" API design that much easier at the cost of maintainability elsewhere. If you want to compare apples to apples, you need to compare F# to other statically typed languages.

Also note that the following is a valid Crystal-lang code:
%w[Peter Julia Xi].map { |name| "Hello, #{name}" }.each { |greeting| puts "#{greeting}! Enjoy your Crystal" }
As they put it:
>Crystal is a general-purpose, object-oriented programming language. With syntax inspired by Ruby, it's a compiled language with static type-checking.
But this time, one can probably say that Crystal will lake the benefits of ecosystem that only a large popular language enjoy.
I guess on that side F#, relying on .Net, is closer to Kotlin with Java ecosystem.

  The only difference is that you have to specify the type of the list when you declare it though... That's not really a big deal.
  List<string> names = ["Peter", "Julia", "Xi"]; names.Select(name => $"Hello, {name}").ForEach(greeting => Console.WriteLine($"{greeting}! Enjoy your C#"))
  or
  new List<string> { "Peter", "Julia", "Xi" }.Select(name => $"Hello, {name}").ForEach(greeting => Console.WriteLine($"{greeting}! Enjoy your C#"))

  Nothing is that much a big deal on a small selected sample, on the one hand on the other. That is, maybe some will prefer mandatory explicit type for every single variable, and some other will prefer type inference whenever possible, and both have pros and cons.
  To jump in a REPL (or any debug breakpoint observation facility), having optional type inference is a great plus to my mind.
  Note that Crystal does allow to make type explicit, and keep the fluent interface on track doing so:
  Array(String).new.push("Peter", "Julia", "Xi").map{|name| "Hello, #{name}"}.each{|greeting| puts "#{greeting}! Enjoy your Crystal"}
  Let’s remark by the way that, like with C# lambda parameters, block parameters are not explicitly typed in that case.

That's exactly what I meant with the two last paragraphs.
