flexvault,
Read perlsub. 
NAME(LIST);  # & is optional with parentheses.
NAME LIST;   # Parentheses optional if predeclared/imported.
&NAME(LIST); # Circumvent prototypes.
&NAME;       # Makes current @_ visible to called subroutine.

Unless I am creating a reference to a sub (my $subref = \&somesub;), I almost never even think about using & with a sub name purely out of habit. The rare exception is when I am using goto &somesub; which @_ gets inherited.
