I'm looping for arguments in a subroutine. How can I loop and shift using the default variable $_ ?

We can do this.. 

sub scribble {
   while ( $a = shift ){
      $a; # has arg
   }
}

What I am trying to flirt with here is.. 

sub scribble {

   while ( shift ){
      $_ ;  # not here!  
   }
}

That I won't have to instance a symbol?

( And I mean, seriously... where the #$!@& is shift output going?? Is its scope only in () ??? )
