I've been thinking about https://code.jsoftware.com/wiki/Vocabulary/fcap and some of my struggles with it, in its current form.
(1) The page covers six different conjunctions, and does not begin to give examples until half way down the page. Conceptually, I would prefer a page dedicated to each in the vocabular, with the diagrams from this page as reference material elsewhere (perhaps an appendix, perhaps a lab, perhaps an introductory document, perhaps repeated from each vocabulary page, perhaps something else). (2) Although the page includes a statement suggesting that it's better to use the dyad form of a fold multiple verb than the monad form, the page contains no worked examples using the dyad form (for example: using numbers or characters). (3) The u argument is an efficiency mechanism, which means sometimes it's best to not use it and put the efficiency elsewhere. (4) The result of the monad use of a fold multiple verb is 1 less than the length of the original list, and that can be useful but it can also take some getting used to. The result of the dyad use of a fold multiple verb is the same length as the y argument. #]F:.,: i.12 11 #1 ]F:.,: i.12 12 ---------------------------- Anyways, I think we need some good canonical examples of use for these conjunctions, so that people can see how things work. (I'll see if I can come up with something... but for now I wanted to leave this here, before I forget about these issues, again.) Do any of you have a nice example or two?
