The most normal C++ program be like:

// prints "Hello, World!"
namespace{decltype(+*"")(*main)()=[]()->decltype(main()){return{};};}
decltype(main())(main(decltype(main())={},decltype(&*"")_[]={})){
extern decltype(&"") puts;
reinterpret_cast<decltype(::main())(*)(decltype(&*""))>(&puts)("Hello, World!");
return(decltype(::main()){});
}
