Did the Perl / Core Foundation bridging break in MacOS 10.11? This used to work:

use Foundation;
my $e = NSHTTPCookieStorage->sharedHTTPCookieStorage->cookies->objectEnumerator;
while (my $c = $e->nextObject and $$c) {
  print $c->domain->cString . ": " . $c->value->cString . "\n"; }

But now:

Can't locate object method "sharedHTTPCookieStorage" via package "NSHTTPCookieStorage" (perhaps you forgot to load "NSHTTPCookieStorage"?)

Previously.
