It isn't hard to find, but my point was that if you say "using an intuitive declarative language" then a developer will get excited by a code snippet that shows that intuitive developer language. It wasn't there, and I think their post could be improved by having less fluffy language and more code, if they are targeting me, that is.
This link does show the code, but it took a few clicks to get there from your links:
The language is CUE, which I think will see mass adoption in config / DevOps in the coming years. So regardless what you think of the language today, it is likely to become important and part of your like in the not too distant future.
That's great context. That should be added to that doc link right at the top, it would have me feel much more safe about investing the time to learn it!
CUE has good pedigree, the creator Marcel wrote the prototype for Borg (k8s), worked on both Google config languages, and worked on the Go team. CUE is how he thinks those Google config languages should have been designed.
Sorry to be that guy but maybe try the docs page...?
