I'm hitting this with the following similar, but different snippet. Maybe it
will help with this.

#include <array>

struct Foo {
    int operator()(int i) {
        return 0;
    } 

    template <std::size_t N>
    auto operator()(std::array<int, N> ids) {
        return std::apply([&](auto...) {
            return operator()(0);
        }, ids);
    }
};

int main() {
    Foo foo;
    foo(std::array{0, 1});
}
