> C lacks the capability to describe fairly widespread functionality: things like fixed-size integer types [0], pointer lifetimes, arrays with lengths, functions with bound environments, variable arguments [1]. Keeping distinctions between binary strings and textual strings would be useful for languages, and tracking how to deallocate pointers would be beneficial as well. An ABI that allows systems with different GCs to pass GC information to each other would be amazing, if challenging. Adding some of those features would mean that every language has to support them and that includes c if you wanted to gain any traction. Part of the reason c is the interop standard is because it lacks those features, the less features you have the easy it is for the rest of the world to inter operate with you.
