Limbic~Region, are you sure of that? I thought this at first too and wrote a piece of code to demonstrate it: 
sub direct(\$\$) {
   print $_[0] . "   " . $_[1] . "\n";
}

sub indirect($$) {
   my ($one, $two) = \(@_);
   print $one . "   " . $two . "\n";
}

my ($first, $second) = qw(Hi there);
print \$first . "   " . \$second . "\n";
direct $first, $second;
indirect $first, $second;
__END__
SCALAR(0x1823c78)   SCALAR(0x224f88)
SCALAR(0x1823c78)   SCALAR(0x224f88)
SCALAR(0x1823c78)   SCALAR(0x224f88)

But the scalar refs point to the same memory address, which is natural for the main program and the direct sub, but completely unexpected (at least for me) for the indirect sub.
Maybe there is a different explanation for this behaviour, though.
