Random
(清單第 (random v) 項項目\( [list v] \) :: list) chooses a random item in the list. Thus, it can be replicated with the following code:

(清單第 (隨機取數 (1) 到 (清單 [list v] 的項目數 :: list)) 項項目\( [list v] \) :: list) This also gives the ability to use lists as a workaround for the 随机取数 到  block.

Last
"Last" gives the last item of the selected list. (清單第 (last v) 項項目\( [list v] \) :: list) Its replica is: (清單第 (清單 [list v] 的項目數 :: list) 項項目\( [list v] \) :: list) // only if length of list > 0
