$ md Mod
$ cat > Mod/Vars.pm
package Mod::Vars;
use vars qw( $CONFIG );
sub f { print "$CONFIG\n"; }
1;
$ cat > Mod/Our.pm
package Mod::Our;
our $CONFIG;
sub f { print "$CONFIG\n"; }
1;
$ perl -we'use Mod::Vars; local $Mod::Vars::CONFIG = 1; Mod::Vars::f();'
1
$ perl -we'use Mod::Our; local $Mod::Our::CONFIG = 1; Mod::Our::f();'
