vote on What operator should perl5porters use for safe dereferencing?

There is an open discussion on perl5porters about adding a new "safe de-reference" operator. This operator would basically cause things like my $foo= $bar-XX>method(); to be "safe" should $bar be undefined, and cause $foo to be equal to "undef". Which operator do you think is appropriate? (Yes for once the poll is serious :-)
