Please try installing Rust with the rustup tool, creating a "Hello world" skeleton CLI tool, and compiling a deployable executable for it. It will take you (not joking) perhaps 10 minutes or less if you have never done anything with Rust before. Then look at how you would add docs and tests. The Rust language is not simple, but the tools are really good. Try the same exercise with Go if you prefer.

If you are willing to give this a try and invest the 10 minutes, you'll understand why I didn't use the phrase "shocking" casually: listing off features doesn't really convey how huge the usability gap is.

It was this:

> "Python best practice: figure out the correct directory structure by reading docs and looking at GitHub repositories, learn how to write setup.py & setup.cfg & requirements.txt & MANIFEST.in files, setup py.test and tox (because Python 2 still lives), write your README in RST format (as used by nothing else ever), and for bonus points: write your own Makefile. Get depressed when you realize that target platforms either don't have Python or have the wrong version."
