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(...); ...
#Update: ++BrowserUk faster fingers!!!

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