Use it (such as list-understanding and generator of Python), where you yield can also be used).

It is applied in combination with and writes a new element in the resulting sequence.

  / ** Command Line Organisms Uppercase * / Object Main {ARF: Array [String]) {val res = for (a

F # will have related expression 

  [ For a args - & gt; A.toUpperCase] ​​
