you're asking why K doesn't have a fleshed-out equivalent to all the functionality popular open-source languages have, to the group of people who were frustrated enough with K being closed-source to take the first painful steps toward independence. It's a lot of work, it requires patience and sustained effort over time, and case in point even the enormous amount of work that has been done already doesn't get rewarded

but in general, macros are mechanisms of abstraction and detail-hiding. APL-family languages eschew obfuscatory abstraction, and aim to provide a toolkit of language features that can be brought to bear directly on a wide range of problems

My impression is that they were only willing to devote so much energy to it as they had bigger fish to fry. I believe it was taken more seriously in the never released kOS. The long and the short of it us that this is fairly blue sky territory in the open source K world. @kyte’s efforts are pretty exciting in that regard.

@AlexanderBelopolsky bitbucket.org/ngn/k is open for contributions now, with a CAA to protect my back. tbh i don't expect code to start pouring in, given the unusual style and the extra step of signing a document, but at least i hope the AGPL might make people more willing to use the language, find bugs, suggest improvements.

@rak1507 yes, but one of the charming (for me) things about the prior unification is that you can replace a function with a cached version of it (array or dict), and in k4 it just worked . Now it only mostly works. There are other "almost equiv but not quite" things; e.g. if you have a list L and a dictionary version of it d:(!#L)!L (! is iota, # is rho).

@KelvinSherlock ah right, gitlab would have been the right choice for that. anyway, i decided it's not worth a bother and made bitbucket.org/ngn/k publicly accessible - it contains just the binary, the tests, and a small sample of my c code
