DirHandle
DirHandle - supply object methods for directory handles
<![CDATA[
use DirHandle;
$d = new DirHandle ".";
if (defined $d) {
while (defined($_ = $d->read)) { something($_); }
$d->rewind;

The DirHandle method provide an alternative interface to the
opendir()
,
closedir()
,
readdir()
, and
rewinddir()
functions.
The only objective benefit to using DirHandle is that it avoids
namespace pollution by creating globs to hold directory handles.
