Thanks for the nice work, I try compare this with a few other options:

1. hcl
2. cue
3. Jsonnet
4. Dhall

I find cue is the most promise one, but it only has go impelement.

cue can verify data with type at once. If we can use ctfe generate cue schema by struct like toml-foolery and auto parse it into D value, it will be a killer feature to attract more people to use D

It's worth pointing out that SDL (as in Simple Declarative Language) isn't being actively developed anymore. I reached out to Daniel Leuck about it a few years ago as there were a few things I'd wanted to see in an updated spec. There was some discussion about an updated specification for SDL but in the end it was decided that development would focus a family of languages under the name of Ki. One of which, Ki Data (KD), is essentially the newer replacement for SDL. As shown in the linked documentation, a *.kd file is similar to *.sdl but there is far more documentation about the newer standard.
