I'd like to be able to mark a struct somehow, so that the only way to construct it is with the designated initializer syntax.
Hypothetical example:
struct FooArgs {
REQUIRE_DESIGNATED_INIT(Foo)
int apple;
int banana;
int cherry;
int durian;
// ...
};
void runFoo(FooArgs);
int main() {
runFoo({5}); // error: you're supposed to use named arguments
runFoo({.banana = 3, .cherry = 4}); // good
}
mathias@mongodb.com suggested this and wrote a POC, and I would find this useful for an upcoming project.
