Thanks for the replies guys, now I got it. I was expecting the value of @_ will remain same (“-w”) throughout the code. But for subroutine formatlist the value of @_ is “-w” and for anonymous subroutine @_ is “Command Line”. I removed the last line  &$arguments(‘Command Line’) from above code, and got “-w out return” printed.
