Bug #91154 for Tree-AVL: perl v5.16.3 reports deprecated use of defined(@array) in Tree::AVL source code

I'm using Tree::AVL version 1.075, installed from the CPAN distribution. Using perl v5.16.3 on OpenBSD 5.4, perl warns of deprecated code in the Tree::AVL source code, even without -w or 'use strict': % cat try-Tree-AVL2 #!/usr/bin/perl use Tree::AVL; % ./try-Tree-AVL2 defined(@array) is deprecated at /usr/local/libdata/perl5/site_perl/Tree/AVL.pm line 1082. (Maybe you should just omit the defined()?) % perl -v This is perl 5, version 16, subversion 3 (v5.16.3) built for amd64-openbsd Copyright 1987-2012, Larry Wall Perl may be copied only under the terms of either the Artistic License or the GNU General Public License, which may be found in the Perl 5 source kit.
