Not in the way it’s supposed to. `foreach (v; aa)` is supposed to 
run over values and `foreach (k, v; aa)` over keys `k` and values 
`v`. From the range interface, `front` can only return one thing. 
If it’s a tuple that can decay into two values, sure the `k, v` 
one works, but the `v` one gives you tuples, not values.
