It matters if you're trying to save and restore something like this: 
sub return_getter_setter {
  my $value = shift;
  (sub { $value }, sub { $value = shift });
}
my ($getter, $setter) = return_getter_setter(42);

If I save both $getter and $setter in the same batch, I'd expect that when they are restored, they still both share the same secret lexical. I do believe that the current code deparser cannot be used for this at the moment, and that it's a difficult task. The problem is that when you deparse the text for $getter, you have to put some placeholder for $value, and when you deparse $setter, you still have to put some placeholder for that $value. But how do you know the two share the same placeholder?
