Great. But you have to simplify the sources.

R is also an array language, but a non-iversonian one. Another good ressource for array languages is https://aplwiki.com/.

r/apljk on reddit is also active.

Maybe the internal broadcasting mecanism in numpy don't allow this nativelly ?

the top comment trick [ n, 1, n + 1, 0 ][n % 4] can be implemented in J as following :

   f =: ]`1:`>:`0:@.(4&|)"0

Then:

   (,. ; #: ; [: #: f) i.16

 0    0 0 0 0    0 0 0 0

Array programming requires true array languages like apl and j.

J has revolutionized the way I think. I can confirm it: ever since I learned to program with it, I’ve been able to solve so many problems that previously felt far beyond my (limited) intellectual reach. For me, J (and by extension, the APL family more broadly) has contributed as much to my thinking as the methodologies I learned during my university studies in philosophy. Suffice it to say, it has profoundly and positively shaken me.

Maybe not everyone involved is quite the genius you might've been expecting.

Maybe codfns for apl will solve this ? That's what I understood.. but maybe I'm wrong.

-: and :- are not the same... Maybe some typos... But your list shows how left and right terms are the same in each identities. Look like some pedagogical stuff.

For instance :

(],[) -: ([,])~

(],[) Appends right and left term while ([,])~ append left and right term after arguments order inversion.

They all fall into the pitfall that Martin Heidegger suggested avoiding, particularly in the introduction of his text What Is a Thing?.

No. In APL deriverd array programming languages, verbs (or functions) are monadic or dyadic : they accept only one or two arguments :

In '1 + 1', + is a dyadic operator, while in 'exp 5', exp is monadic.

In J, and in APL I guess, left arg is usually understood as 'control data', while right arg is the data upon which calculation is done. Left argument is usually left unchanged after calculations.

In this way, is it possible to create multi-arguments verbs, by placing boxed args on the left of the verb.

Better : people have to Guess on day 1 a random value generated on day 2, and the winner would be awarded with a Big amont of money. Privacy granted. Lottery. Lottery IS a Time traveller detection device.

Both the 1979 and 1983, C and Pascal versions, compile fine and work as expected using last versions of respectively TCC and Lazarus on windows 10.
