In fact, if it weren't for the rules that force the initializations to
appear in declaration order, one could just suggest to use designated
initializers as a practical workaround:


struct foo_arguments { int x; double y = 3.14; string s = "hi"; };
void foo(foo_arguments);

foo({.x = 42; .s = "hi!"}); // OK, y = 3.14
foo({.y = -1}); // OK, x = 0, y = -1
foo({.y = -1, .x = 42}); // ERROR, cannot reorder
