CUE is great - it's the first config language I've used that feels like it's getting things right.

I've been playing with some different ways of using CUE:

- https://github.com/cuebernetes/cuebectl (declarative, continuous syncing with a kube cluster)

- https://github.com/ecordell/cuezel (bazel/make but with CUE)

both have some overlap philosophically with the "command" subsystem in CUE, but it's been fun to play with different approaches to the same problems.
