Re: Perl Subroutines Call

[ph0enix]

From perlsub. To call subroutines:

   1. NAME(LIST); # & is optional with parentheses.
   2. NAME LIST; # Parentheses optional if predeclared/imported.
   3. &NAME(LIST); # Circumvent prototypes.
   4. &NAME; # Makes current @_ visible to called subroutine.

Personaly I prefer to use NAME(LIST); and prefix & only in special cases like &$code.
