If $__ is a reference to our lvalue, if any, instead of an alias, since
references are all scalar, we can take C<ref($__)> to get a finely
grained C<want> function.

And when the sub is called in list context, @$__ will be the list.
This allows intrusive functionality to fiddle with lvalue parts:

	sub DirectBubbleSort(){
		my ($i,$t) = (-1,0);
		while (++$i <= $#$__){
			$$__[$i] > $$__[1+$i] and $t++ and @$__[$i,1+$i] = @$__[1+$i,$i];
		};
		$t and @$__ = DirectBubbleSort;	
	}

	@SomeList = DirectBubbleSort; # instead of DirectBubbleSort(\@SomeList)
