Ada does this with the rather convenient pragma Export(Convention => C, Entity => My_Ada_Function, External_Name => "mypackage_ada_function"); You can kinda coerce D and C++¹ to do the same thing, but this is definitely something Rust and Ada got really right. -- ¹Okay I lied, C++ does this pretty easily with extern "C". However, C++ APIs frequently do not convert well to C at all and you often have to write wrappers for them. C++ classes in particular just can't cross ABI boundaries without a lot of pain, while Ada records and Rust structs are usually just a pragma away from being accessible from C (their “methods” don't use a special calling convention; method calls are just syntactic sugar for passing a struct as the first argument).
