The definitions can be declarative but generated from code

I think we need something like samurai/ninja for terraform, that would be sweeeeet

I believe you just discovered cdktf https://github.com/hashicorp/terraform-cdk#cdk-for-terraform

Also, I couldn't search for samurai in order to know if it's "jinja2 for $other_language" or what, but I just inferred that you wanted a templating language to generate terraform files
