+vars - Perl pragma to predeclare global variable names
=head1 SYNOPSIS
=head1 DESCRIPTION
-NOTE: For variables in the current package, the functionality provided
-by this pragma has been superseded by C<our> declarations, available
-in Perl v5.6.0 or later. See L<perlfunc/our>.
+NOTE: For use with variables in the current package for a single scope, the
+functionality provided by this pragma has been superseded by C<our>
+declarations, available in Perl v5.6.0 or later, and use of this pragma is
+discouraged. See L<perlfunc/our>.
This will predeclare all the variables whose names are
in the list, allowing you to use them under "use strict", and
