[] and do { my @array; \@array }, will both create an array and return a reference to it, but the array will be anonymous. No good.

You could use prototype trickery to do what you want. 

sub get_array_ref(\@) { $_[0] }
GetOptions( 'array=s' => get_array_ref(my @array) );
print("@array\n");

By the way, it's =s when you pass a reference to an array, and =s@ when you pass a reference to a scalar. That opens up another possibility: 

GetOptions( 'array=s@' => \(my $array) );
print("@$array\n");
