Thoughts on the Rascal meta-programming language

  8 10 7.9 OCaml

  A language for certifying specification

Of course. Here was the first incarnation: https://github.com/amw-zero/sligh. It has a decent overview of the idea in the readme. To sum it up here, the idea is: have a language built around model-driven development and model-based testing, where you write a simple model of an application, and the implementation and model-based tests are compiled for you. I wrote about the overall model-based testing strategy here. This idea comes from self-certifying compilers that produce proofs of their correctness such as Cogent, but we drop the formality requirement and use property-based testing to compare the implementation and model.

So, full compilation of the implementation is out in my mind, and the next best thing is at least deriving the implementation from the model so you can leverage the logic you've already defined. That's where metaprogramming comes in, and that's what I'm playing around with here.
