This has some pretty great ideas within it. A few that stuck out to me in case others don't want to skim the full spec:

Start with YAML/JSON/TOML, but then add:

- Optionally strict typing and structs

- Inheritance

- Dynamically computed properties

- Functions & object methods, which are really more like computer properties

- If/Else conditionals, which are really more like a ternary

.. and managed to do it while still making it look like a simple config file.

The closest analogue from memory might actually be Terraform.

The one thing that had me squinting was the object extension syntax. It looks powerful.. and I understand its value.. but wow that's ends up being eye-full of () {} and [] all in one code bock.

Don't forget what's removed when compared with YAML... white space as nesting.
