`Appender` only exists so that you can continually append to a 
dynamic array without the GC having to look up its `capacity` for 
every append. `Array` already keeps track of its own 
[`capacity`](https://dlang.org/phobos/std_container_array.html#.Array.capacity), so you don't need to use an `Appender` on it, just use `Array` on its own.
