I will be happy for you guys to do whatever you think makes the
documentation best. We are all beginners with Fold.

I strongly support this. Folds belong at the core

introduced, I, too, was disappointed by the lack
of easily understood and adaptable examples.
At least that’s the way things were then.
But I was happy seeing them introduced.
On one thing, I disagree, though.
They may share that common umbrella page,
but I think it should point to six subpages.
The way I (don’t) understand them, they are
conceptually too close for users to be taught
about them seperately.

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?
Thanks,
