=head1 NAME

vars - Perl pragma to predeclare global variable names

=head1 SYNOPSIS

use vars qw($frob @mung %seen);

=head1 DESCRIPTION

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functionality provided by this pragma has been superseded by C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 pragma will predeclare all the variables whose names are
in the list, allowing you to use them under C<use strict>, and
disabling any typo warnings for them.

Unlike pragmas that affect the C<$^H> hints variable, the C<use vars> and
C<use subs> declarations are not lexically scoped to the block they appear
in: they affect
the entire package in which they appear.  It is not possible to rescind these
declarations with C<no vars> or C<no subs>.

Packages such as the B<AutoLoader> and B<SelfLoader> that delay
loading of subroutines within packages can create problems with
package lexicals defined using C<my()>. While the B<vars> pragma
cannot duplicate the effect of package lexicals (total transparency
outside of the package), it can act as an acceptable substitute by
pre-declaring global symbols, ensuring their availability to the
later-loaded routines.

See L<perlmodlib/Pragmatic Modules>.
