Does list flattening still occur in this case necessitating the use array references if you want to pass one array per parameter?
sub calls always flatten into @_. the only way to pass individual arrays is by reference. prototypes (not recommended in most cases) do allow arrays to be parsed as single args but they are actually passed as references.
