There is no official Perl style. Currently I leave the & off and always put parens in so that I can keep the same style in several languages. YMMV.

However as others have said, if you're using functions from package A in package B, I'd strongly recommend using Exporter in package A so that package B can explicitly import the functions that it uses.
