Here:
template <class F, class X, class Y>
struct Foo {
Foo(F, X, Y y) : y_(y) {}
Y y_;
union FooHolder {
int foo;
};
[[no_unique_address]] FooHolder foo_holder_;
};
template <typename Factory, typename X, typename Y>
void MakeFoo(Factory f, X x, Y y) {
Foo(f, x, y);
}
void Start() {
MakeFoo(0, int(), [] {});
}
