our $VERSION = '1.05';

=head1 NAME

DirHandle - (obsolete) supply object methods for directory handles

=head1 SYNOPSIS

# recommended approach since Perl 5.6: do not use DirHandle
    if (opendir my $d, '.') {
        while (readdir $d) { something($_); }
        rewind $d;
        while (readdir $d) { something_else($_); }
    }

# how you would use this module if you were going to
    use DirHandle;
    if (my $d = DirHandle->new(".")) {
        while (defined($_ = $d->read)) { something($_); }
        $d->rewind;
        while (defined($_ = $d->read)) { something_else($_); }
    }

=head1 DESCRIPTION

B<There is no reason to use this module nowadays.>

The C<DirHandle> method provide an alternative interface to the
opendir(), closedir(), readdir(), and rewinddir() functions.

Up to Perl 5.5, opendir() could not autovivify a directory handle from
C<undef>, so using a lexical handle required using a function from L<Symbol>
to create an anonymous glob, which took a separate step.
C<DirHandle> encapsulates this, which allowed cleaner code than opendir().
Since Perl 5.6, opendir() alone has been all you need for lexical handles.
