Make sure you know what you are doing when adding & to the front of a function call. It can have unintended consequences if you do not understand the difference. Here is the relevant section from perlsub that briefly explains the difference:
To call subroutines:
NAME(LIST); # & is optional with parentheses.
NAME LIST; # Parentheses optional if predeclared/imported.
&NAME(LIST); # Circumvent prototypes.
&NAME; # Makes current @_ visible to called subroutine.
