Only supports classes with a single (non copy non move) constructor (without default values), until overloading is supported. Based on #5878. C++ Interop Demo: ```c++ // hello_world.h #include <cstdio> class C { public: C(int x, int y) : x_(x), y_(y) {} int x() const { return x_;} int y() const { return y_;} private: int x_; int y_; }; void hello_world(C* _Nonnull c); ``` ```c++ // hello_world.cpp #include "hello_world.h" #include <cstdio> void hello_world(C* _Nonnull c) { printf("C.x = %d. C.y = %d\n", c->x(), c->y()); } ``` ```carbon // main.carbon library "Main"; import Cpp library "hello_world.h"; fn Run() -> i32 { var c : Cpp.C = Cpp.C.C(1, 2); Cpp.hello_world(&c); return 0; } ``` ```shell $ clang -c hello_world.cpp $ bazel-bin/toolchain/carbon compile main.carbon $ bazel-bin/toolchain/carbon link hello_world.o main.o --output=demo $ ./demo C.x = 1. C.y = 2 ``` Part of #5880.
