The types you list are the basics. All other cases are covered by "If the referenced object has been blessed into a package, then that package name is returned instead."

For regular expressions, this is demonstrated by: 

use Scalar::Util qw/blessed/;
$q=qr//;
print ref($q);
print blessed($q);
__END__
