Unfortunately, you both "don't *need* to" and "*can* do" anything in
perl.  Often at the same time!  This is what leads to very difficult
to read, and more difficult to maintain perl code.

While you don't *need* to put parenthesis around the args to split, or
most any perl function, and you don't *need* to specify the default
pattern match target, it is considered a "best practice" to do so.

I highly recommend Damian Conway's book "Perl Best Practices", which
outlines these and many other useful pieces of advice.
