That means *always* put the array in the shift.
Here's another opinion, for balance. When you explicitly write something that's implicit you make me stop and wonder why you have done so. What have I missed in reading your code that requires you to write something that otherwise wouldn't be there? Why have you felt the need to unduly clutter your code with extraneous punctuation? The additional text acts as a warning to tell me that all here it not as it seems. Your code may be correct, but it is not idiomatic. You may be attempting to increase clarity but you are, in fact, impairing comprehension. As I said, it's another opinion. There is a reason why Perl has defaults.
