`T[] dynArr` can be passed (by reference) to a function that

```d
void add1(ref int[] nums) {

}
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.
Makes sense. Thank you
