Test: 999
TPP: statement -> statements (number == 999 is a statement)
In fact, I have been this transformation along with the previous few transformations already. I kept adding "number == 121" like statement to the if condition. I think this transformation is a sub-transformation comparing to the previous ones which are major transformation and changes the execution path to more generic code.
Until just now, I found there was no transformation happened in that execution path. So, I do this transformation again and then "refactor" those statements into a more generic statement which can fully present them.
