On Preserve @_ aliasing a (scalar||array) I wrap a scalar parameter into an array while preserving it's aliasing. A problem I've just encountered it that it doesn't preserve the aliasing on the $list container itself, and I think it's because "return $x" returns a copy of whatever and I can't think of an aliasing equivalent...

If that made no sense it doesn't really matter. I want a sub "ret" which will print "ALIAS" below 

  DB<28> sub ret { return $_[0] }

  DB<29> $a = []; print \$_,"\n",\$a and \$_==\$a and print "ALIAS" fo
+r ret($a);

SCALAR(0x8201b08)

What I want can probably be achieved in two steps: 
&wrap_arg_one; for my $list ($_[0]) { ...}

but I'd prefer something like &shift_list in the post above
