Okay.  Here is the current (all-passing) t/data_types/nested_arrays.t:

    {
	my @a = (1,2,[3,4]);
	my $a = (1,2,[3,4]);
	my @b = [1,2,[3,4]];
	my $b = [1,2,[3,4]];
	my @c = (1,2,(3,4));
	my $c = (1,2,(3,4));
	my @d = [1,2,(3,4)];
	my $d = [1,2,(3,4)];

	is(+@a, 3, 'Array length, nested []');
	is(+$a, 3, 'Array ref length, nested []');
	is(+@b, 1, 'Array length, nested [], outer []s');
	is(+$b, 3, 'Array ref length, nested [], outer []s');

	is(+$c, 4, 'Array ref length, nested ()');
	is(+@c, 4, 'Array length, nested ()');
	is(+@d, 1, 'Array length, nested (), outer []s');
	is(+$d, 4, 'Array ref length, nested (), outer []s');
    }


Please sanity-check. :-)

Thanks,
