I'm sure that this is a fairly simple question, but its still giving me fits. How do you share variables when using Safe? There isn't a lot of documentation on Safe.pm and I can't seem to figure this out. The following code *should* print 7 when its run. Instead it doesn't print anything.

use Safe;
my $maxCounter = 7;
my $testCode = 'return $maxCounter;';
my $container = new Safe;
$container -> share('$maxCounter');
print $container->reval($testCode)."\n";
