:::Hi Ledrug, that's brilliant! Why not make a task of maybe:
:::: ''Create a function "s_of_n_creator" that given n, returns a function "s_of_n" that when called with successive items <strike>from a list</strike> returns an equi-weighted random sample of n elements from its arguments since creation using Knuths Algorithm S. Test your function by printing and showing the frequency of occurrences of the selected digits from 10000 repetitions of using the s_of_n_creator(3) and for each s_of_n using the last set of 3 elements when it is given the integers 0..9 inclusive, in order.''
::::: Huh? I don't quite understand that description, but it seems like an entirely different task. Since there are already several implementations, I don't think it is good idea to rename the task and change the task description. Further, I don't really see the purpose of "function that returns a function". In any case, that requirement means that only a small fraction of languages can be used to implement the task. That is another reason to not change this task. If you want such a task, make it a new task. --[[User:PauliKL|PauliKL]] 14:05, 21 October 2011 (UTC)
:::::: Hi PauliKL, The idea is to create an entirely new task not a re-naming of this one. I'll flesh out the description a little, and choose the name wisely.
:::::: Check out [[Accumulator factory]] which is another task that required a function returning a function and has over fifty entries, so I expect there are a considerable number of languages that could implement what I have in mind. --[[User:Paddy3118|Paddy3118]] 16:59, 21 October 2011 (UTC)
:::Or I could do this if you like this weekend? --[[User:Paddy3118|Paddy3118]] 06:37, 21 October 2011 (UTC)
:::: Sure, you do that. The exact reference is ''The Art of Computer Programming'', Vol 2, 3.4.2 p.142. I can't seem to find any ref online, though. Also, don't name it "m of N lines in a file"-- --[[User:Ledrug|Ledrug]] 11:34, 21 October 2011 (UTC)
