The idea of a multi-lingual programming language is so interesting. The fact that there is a lingua-franca for programming is, ironically, both a huge boon for accessibility and a large hurdle. With a single programming language any programmer only has to learn one language to gain access to the vast majority of programming languages and codebases. But if you are not already a native speaker, learning that common language can be a significant barrier to entry. This isn't new, of course, we've had several eras of different lingua-franca in science, for example (Latin, German, etc.).

Looking at it more, Hedy looks like it solves the latter problem reducing the barrier to entry. I wonder if something like this could be used to also keep the benefit of a common language. It looks like it allows you to choose at the beginning what language to use for authoring code, but could you use it's mapping of keywords across languages to allow a reader to choose the language they view the code in? Would that be sufficient? Maybe not because you still have variable names, function names, etc. that wouldn't have such a mapping. But I wonder how far that kind of auto-translation would get you. And how effective AI-based translation of the remainder would be, especially if paired with some sort of AST-based tooling that helps the AI to use consistent naming for the same symbols, etc. Interesting!
