Well, first, "my" isn't a function. Is the reason that so many people
write my ($x) = 1; because people think it is? Hmmmm.
But on to your question. Have you looked at perlstyle?
· Omit redundant punctuation as long as clarity doesn't
suffer.

Along the same lines, just because you CAN omit
parentheses in many places doesn't mean that you ought
to:
return print reverse sort num values %array;
return print(reverse(sort num (values(%array))));
When in doubt, parenthesize. At the very least it
will let some poor schmuck bounce on the % key in vi.
Even if you aren't in doubt, consider the mental
welfare of the person who has to maintain the code
after you, and who will probably put parentheses in
the wrong place.
I like the first point. I have looked at code with redundant
punctuation trying to work out the hidden gotcha that necessitated the
punctuation. Leave it out if you can reasonably do so.
