Nice post. If i understand you correctly; you are saying that K is specialized enough (my knowledge is only cursory here) that you can directly work with the data model easily rather than going through multiple layers of abstractions and hence linear code is normal. In other languages it may not be so easy to do and multiple layers of abstractions only make things harder to comprehend. True, IMO Abstraction should always follow Understanding of the Problem space and not some arbitrary dogma. What i find infuriating nowadays is "cargo culting" where people blindly follow something because they read it somewhere/listened to somebody without thinking through the motivations involved and whether it is applicable to their current problem. In other words "they don't think" for themselves. Examples are "OO is bad"(it is not), Agile/Scrum processes will magically solve all your PM problems(hell, no!), Using the latest library/framework/API/fad will magically make your system better (no!), etc. etc.

Yes, it is often just easier to write the linear code than figure out if you can reuse anything because the space is small. I think a good 'feeling' for this is, if you need internet search/package managers/copilot etc for something or if you can just write working code sitting on a desert island, quite possibly on paper. For instance, for C, asm (arm/68k/z80/8080 and older intel), k and some others I can write working code like that for non-toy applications in specific domains. And, at least for me, those languages lend themselves very well for this linear programming. Incidentally, but not related, this is for me also the most enjoyable way of programming; I kind of really hate using libraries. That's also because we work in heavy regulatory areas where you cannot just add them; you have to inspect them and sign of on them and, of course, most of them are terrible...
