This should actually be formatted as to be fair contender to the
procedural example:

$ret =3D scandir($arg)
  |> array_filter($$, function ($x) {
    return $x !=3D=3D '.' && $x !=3D=3D '..';
  })
  }> array_map(function ($x) use ($arg) {
    return $arg . '/' . $x;
  }, $$)
  |> getFileArg($$)
  |> array_merge($ret, $$);

Not a big difference now...

$files =3D scandir($arg);
$files =3D array_filter($files, function ($x) {
  return $x !=3D=3D '.' && $x !=3D=3D '..';
});
$files =3D array_map(function ($x) use ($arg) {
  return $path . '/' . $x;
}, $files);
$ret =3D array_merge($ret, getFileArg($files));

=2E..the only thing that bugs me in the procedural code is the fact that
array_filter and array_map take their arguments in different order. :P
