perldoc perlsub (http://perldoc.perl.org/perlsub.html) explains the '&' is entirely optional - except where it isn't - e.g. where you might need to check if the subroutine exists, use a reference to a subroutine rather than a direct call etc. There are provisos to the use of the '&' prefix and the documentation explains those.
