These are the big ones I use, specifically because of the standard libraries:

Python (decent standard library) - It's pretty much everywhere. There's so many hidden gems in that standard library (difflib, argparse, shlex, subprocess, cmd)

C#/F# (.NET)

C# feels so productive because of how much is available in .NET Core, and F# gets to tag along and get it all for free too. With C# you can compile executables down to bundle the runtime and strip it down so your executables are in the 15 MiB range. If you have dotnet installed, you can run F# as scripts.

These are definitely some good thoughts, thanks!

Do you worry at all about the future of F#? I've been told it's feeling more and more like a second-class citizen on .NET, but I don't have much personal experience.

		I used to, but the knowledge of .NET seems mostly transferrable to C#. It's super useful to do `dotnet fsi` and then work out the appropriate .NET calls in the F# repl.
