Hello, is there some structure in standard library that acts like Appender but works also on std.container.array Arrays ? I'd like to have the capacity of Arrays doubling every time new memory is allocated. Appender requires the input to be a dynamic array, which is not the case for std.container.array Arrays.
`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.
