Tuple indexing has same problem.

template TypeTuple(T...){ alias T TypeTuple; }

struct tuple
{
    TypeTuple!(int, int) field;
    alias field this;
}

auto front(T)(ref T arr){ return arr[0]; }

void main() {
    auto bars = [tuple(0, 0), tuple(1, 1)];
    auto spam1 = bars.front[1];      // indexing
    auto spam2 = bars.front[1..2];   // slicing
}
