use_std: command not found

[sshine]

Does this setup make assumptions about what's installed on the system?

• If I search for use_std: command not found, it seems to be related to C/C++ packages being available?
• "devshells" appears to be a typo from "devShells"? Changing it, though, errors with "attempt to call something which is not a function but a set", so that's not right either.
