DirHandle - supply object methods for directory handles
use DirHandle;$d = DirHandle->new(".");if (defined $d) { while (defined($_ = $d->read)) { something($_); } $d->rewind; while (defined($_ = $d->read)) { something_else($_); } undef $d;}TheDirHandle method provide an alternative interface to the opendir(), closedir(), readdir(), and rewinddir() functions.
The only objective benefit to usingDirHandle is that it avoids namespace pollution by creating globs to hold directory handles.
