Hum... Every time I see Nix cited somewhere, it's somebody who tried it and didn't manage to get expertise out of the documentation maze. (You can add me there too.)

But it's no wonder that people keep commenting that Nix is an awesome idea that solves a lot of problems. That's because it's an awesome idea that solves a lot of problems (yeah, like Rust).

It is also completely undiscoverable (not completely unlike Rust), and that's why almost nobody uses it. But that's a matter of improving the documentation or maybe fixing one or two superficial problems on the language.
