Dhall is advertised as a configuration language but you can do a tad more. I use it in my blog-engine to fit a use-case I found was poorly addressed by other approaches: small-cardinality datasets that benefit from type-checking and templating (e.g., list of notes, a photo gallery). I don't claim the idea is especially novel but I found the use case rare and interesting enough to write some explanations, design, and a demo here: https://lucasdicioccio.github.io/dhall-section-demo.html
