DirHandle(3)

NAME
DirHandle - supply object methods for directory handles

SYNOPSIS

    use DirHandle;
    $d = new DirHandle ".";
    if (defined $d) {
        while (defined($_ = $d->read)) { something($_); }
        $d->rewind;
        while (defined($_ = $d->read)) { something_else($_); }
        undef $d;
    }

DESCRIPTION
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.
