naming subroutine reference parameter?

How do you name subroutine reference parameter in perl? Naming a local or pass by value is by simply using my ($param1, $param2) = @_ ; How about by reference? I think it would be harder if I'll be using $_[0], $_[1] direct method. Is it possible? Thanks. -- To unsubscribe, e-mail: [EMAIL PROT
