In the Filesystem guide https://zig.guide/standard-library/filesystem/ the first code snippet is not logically valid. The line: ```zig const bytes_written = try file.writeAll("Hello File!"); ``` is not correct, because `file.writeAll` has return type of `WriteError!void`, so variable `bytes_written` is always `void` in this case. `bytes_written` can be gotten if we replace `writeAll` by `write`, but I don't think we want to do that in this example.
