It depends on the semantic requirement.
If the requirement is "ensure that the array length is at least one, and
then write the first element" then it would be:
```d
if(arr.length < 1) arr.length = 1;
arr[0] = "my string"; // btw, literals will auto-convert to the right width
```
If the requirement is to add another element to a known zero-length
array, then it would just be:
```d
arr ~= "my string";
```
