/*不如RightComposition快

/*比RightComposition慢
Ken Kang说, 这是因为后缀是静态解析的, 而且/*优先级有点低
HongYang Cao做了性能测试:

1. Range[1000,9999]//
2. Select[PrimeQ]//
3. GroupBy[IntegerDigits/*Sort]//
4. Values//
5. Map[Subsets[#,{3}]&]//
6. Catenate//
7. Select[#.{1,-2,1}==0&]//
8. AbsoluteTiming
10. Range[1000,9999]//
11. RightComposition[
12. Select[PrimeQ],
13. GroupBy[IntegerDigits/*Sort],
14. Values,
15. Map[Subsets[#,{3}]&],
16. Catenate,
17. Select[#.{1,-2,1}==0&],
18. AbsoluteTiming
19. ]
