I'm not sure I'd want that second print "@_\n" to print aaa bbb.
I'd want it to. Consider this: 
my @a = qw(aaa bbb);
my $r = \$a[0];
@a = ();
print $$r;

I'd expect that to print "aaa". This is pretty much at the heart of the reference-counting model at the heart of perl. Similarly to how the fact that the lexical var getting freed on scope exit doesn't free the return value in: 
sub f { my $x = ...; return $x }
