Confused on the os module, how to use it?

The os module was introduced 2023-05-08 (two months ago) and will be included in the Elvish 0.20 release.

P.S., When reporting issues it's important to include the Elvish version you are using; e.g., the output of put $version or elvish --version.

I'm using the latest stable release (0.19.2). We should document about the minimum elvish version here:
