I haven't tried F# because I am already having to work with powershell and C# and that whole .net/visualstudio ecosystem. The last thing I will look at on my personal time is a language in that ecosystem but since you recommended it I will have a look.
Since we have a Unity product, I’m moving us to an F# backend! I actually quite like it since we’re building a typical web api for a game.
You don’t have to deal with the typical need to determine what packages to use as you would in ocaml. I have aspnet and co. I’m okay with OOP leaking here and there when I get most of what I need already: an ML tool with an huge ecosystem.
