Your code seems pretty good to me :)

Just one minor comment:

```d
File file = File(filename, "w");
scope(exit) file.close;
```

You don't need to close the file because that's done 
automatically as the `file` goes out of scope (as explained [in 
the docs](https://dlang.org/library/std/stdio/file.html)).

I believe it uses 
[RefCounted](https://dlang.org/library/std/typecons/safe_ref_counted.html) to do that.
