You can't pass an array to a sub. You can only pass a list of scalars.

Whatever you passed ends up in @_. There's no way for the sub to know how
this data was passed, if it matters.

If your sub just needs a list of values, what you've done is fine. If your
sub somehow needs to know about the @fields array, perhaps to modify it or
add or remove elements, you have to pass an array reference. Then you
manipulate the array via the reference inside the sub.
