What about making C<ref bless [], 0> return "main::0" ? It's a true value
and it's a correct package name. And with that the documentation can
be restored to its previous state if you like.

(although I prefer stating clearly that ref() returns an empty string;
I don't know why, I thought that ref(undef) was undefined.)
