I agree. I think Zig is the best at pretending to operate with C, but it's still pretend. You need to do special stuff to interoperate with C. Disclaimer: I'm biased because I'm trying make a C killer even better than Zig is.

  Well, it's still a work in progress, but I have some docs. It's called Yao. The main repo is https://git.yzena.com/Yzena/Yc https://git.yzena.com/Yzena/Yc , which is a monorepo that has other stuff as well. Yao defines two types of files. A "package" file defines stuff that a package can export. A package file looks like this: https://git.yzena.com/Yzena/Yc/src/commit/c0ade4cc5b/build.pkg.rig https://git.yzena.com/Yzena/Yc/src/commit/c0ade4cc5b/build.p... . A "script" file is straight code, like a script. For a package, it is equivalent to `init()` functions for packages in Go. For a program, the main script file is the `main()`. A script file looks like this: https://git.yzena.com/Yzena/Yc/src/commit/c0ade4cc5b/build.rig https://git.yzena.com/Yzena/Yc/src/commit/c0ade4cc5b/build.r... . Note: once the compiler/interpreter is at MVP, those two files will be working code. They will be the build scripts of the repo. Speaking of the build scripts, the language has a way to allow users to define keywords. The build system already uses that to define its own keywords, turning Yao into a build system DSL. (Yes, the first program written in Yao will be used to build Yao. It's a great test of the language.) An example file, with explanation comments, is at https://git.yzena.com/Yzena/Yc/src/commit/c0ade4cc5b/src/yao/example.y https://git.yzena.com/Yzena/Yc/src/commit/c0ade4cc5b/src/yao... . All of the docs are at https://git.yzena.com/Yzena/Yc/src/commit/c0ade4cc5b/docs/yao https://git.yzena.com/Yzena/Yc/src/commit/c0ade4cc5b/docs/ya... , but they are mostly design docs. I think that should be enough links to get you started. Pay particular attention to the example.y file w.r.t. C interoperability. The basic points are: * Every function and type is associated with a C symbol, even if overloaded. * Structs are laid out exactly like C. (There will be another compound type that won't have that guarantee, but it won't be default, and it, too, will have a C ABI.) * It will have unions and enums like C. * It will always use the C ABI, defining extensions to it for things like methods, and those definitions will be defined in the spec that every Yao compiler has to adhere to. * It will always have the option to compile to C. C will be its bootstrap language. That said, I still think there are many weaknesses in Yao compared to C. I don't have much confidence it will actually be a C killer, mostly because I'm not sure anymore that it is possible to add to C and kill it.
