Idiom #180 List files in directory

Create list x containing the contents of directory d.

x may contain files and subfolders.
No recursive subfolder listing.

#include <dirent.h>
struct dirent ** x = NULL;
int n = scandir (p, &x, NULL, alphasort);
(def x ((comp file-seq clojure.java.io/file) d))
using System.IO
var files = Directory.GetFiles(dirPath);
import std.file;
auto x = dirEntries(d, SpanMode.shallow);

import "io/ioutil"
x, err := ioutil.ReadDir(d)
import java.io.File;
final File directory = new File(dirPath);
final File[] files = file.listFiles();
$x = scandir($d);
FileUtil
x := FindAllFiles(d, '*', False);
SysUtils, Classes
  if FindFirst(IncludeTrailingPathDelimiter(d) + '*', 
               faAnyFile and (not faDirectory), SR) = 0 then
  repeat
    x.Add(SR.Name);
  until FindNext(SR) <> 0;
  FindClose(SR);

x = Dir.children(d)
use std::fs;

Do you know the best way to do this in your language ?
New implementation...
