Note that omitting the parentheses is bad style, if your goal is actually to assign the one-element list (0) to the array.
Nit: it doesn't really matter, for one-element lists. There's no difference between a one-element list with and without parentheses. Parentheses don't create lists--they group comma-separated expressions.
The reason you need parentheses in:
my @fib_nums = 1, 1, 2, 3, 5;
... is to disambiguate precedence, not to construct a list.
