=head1 NAME

vars - Perl pragma to predeclare global variable names (obsolete)

=head1 SYNOPSIS

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

=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by this pragma has been superseded by C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>.

This will predeclare all the variables whose names are 
in the list, allowing you to use them under "use strict", and
disabling any typo warnings.

Unlike pragmas that affect the C<$^H> hints variable, the C<use vars> and
C<use subs> declarations are not BLOCK-scoped.  They are thus effective
for the entire file in which they appear.  You may not rescind such
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>.
