Looks nice. I kind of like the allure of using this alongside `jq` as a kind of read/write combo.

Is it possible to create entire hierarchies with this tool or just flat lists? I imagine something like `jo x=$(jo y=...)`, but then you run into the problem of differentiating between regular strings and subcommands.

I pointed your comment to the author, and he updated the examples to mention this possibility :

Thanks!
