can we get a short preview without having to ask for early access? a new language from Google, without the need to use incompatible yaml declarations? sounds just like the next incompatible declaration language, probably unrelated to googles dagger 2 (https://github.com/google/dagger)

The language is CUE, it is a separate open-source project: https://cuelang.org

Dagger uses CUE but you can use CUE without Dagger.

not much info on the site really.
