Thanks for your comments.

1. The missing case 81 is added.
2. I will implement `case 1` and `case 3` later in another patch. BTW: Total amount of these two cases is small, and they even have redundant values with `case 2`, so how about implementing them without `foreach`, just standalone `Pat` one by one ?
