`T[] dynArr` can be passed (by reference) to a function that takes `ref T[] data` but `T[10] data` cannot? Why not?
```d
void add1(ref int[] nums) {
nums ~= 1;
}
unittest {
int[] nums;
nums.add1;
nums.add1;
nums.add1;
assert(nums == [1, 1, 1]);
}
```
the `ref` allows `add1` to extend the length of the slice passed
to it, with potential reallocation. This doesn't make sense with
a static array whose length can't be modified.
