in reply to Forward declaration of subs

Hi perlaintdead,
With forward declaration of subroutine, you can omit the parentheses usage like thus: 

use warnings;
use strict;

 sub printer;

 printer 'hello','world','again'; # NOTE HERE

 sub printer{
   print $_,$/ for @_;
 }

Without the forward declaration one would have to do 
...
printer(...);
...

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
