But in order to make it work you would need all the programs to start using the CLR. It's all of nothing. And if one of languages stops being supported - e.g. not receiving bindings for new libraries - you need to rewrite whole codebase to something different. In case of the "high level" language you just need to transpile it to one of the supported languages and continue development in the output language. > designing something that is the least common denominator between all languages My vision is rather finding some patterns, higher abstractions in various languages: e.g. imperative loop summing squares of all odd elements is semantically similar to filter -> map -> fold functional chain. Building whole language on such patterns will definitely be hard, but I believe it is possible and worth pursuing.
