AssembleRunery was good enough for the Ancestors, and it's still good enough now, by Morgrim.
Great, now you guys have me writing up a longer and sillier list.
Warhammer Faction Programming Languages:
Elves write in Lisp: invented at the dawn of time, looks incomprehensible to normal humans, full of elegant curvature, mostly stays aloof and distant from every other language.
Imperials write in Java: it only sometimes explodes, it's full of squiggles and messy bits, there's a lot of rote chanting of "public static void main String args" by people who don't really understand what they're doing but it seems to work.
Dwarfs write in Rust: full of safety guarantees to prevent unwanted exploding, but it's complicated and intimidating and obscure enough that it's rarely seen outside the Dwarf Programming Guilds.
Vampires write in C: in many ways similar to Java, but more powerful and more dangerous and even more likely to explode if you're not a vampire with a hundred years of experience.
Tomb Kings write in COBOL: it's ancient, it's full of traps for the unwary, if it's in working order you probably shouldn't touch it or you'll get blamed for everything that goes wrong.
Slann write in Assembler: the raw power of the universe at your fingertips, but it takes ages to read through it trying to understand the Great Plan, and a typo can easily mess up everything instead of just being a syntax error.
Chaos writes in Perl:
OCR'ed paint splatter is a valid program, everyone else thinks this is bullshit hax and the chaos gods cheat, that shouldn't work.
Skaven write in PHP: it's a fractal of bad design propped up by Warpstone, C wrappers, and a kitchen-sink/copy-paste design style. Regularly collapses but there's always more.
The Golden Age wrote in Python: the elves streamlined the keywords and design of the language, the dwarfs demanded everything must be precisely and exactly indented.
No, dwaves code in Java: it's pretty good with objects, not so with more abstract models; it's good for banks and enterprise application but too cumbersome for bashing an MVP together in a week; it's big on inheritance; it's pretty depending on Ancestor Corporations.
Humans code in JavaScript: allegedly inspired by Java but nothing like it; really messy but very prolific; multiparadigmal but using multiple paradigms at once results in Dhar; ecosystem changes very fast.
You have a valid point.
Orcs program in Matlab: Nobody, including the users, is sure if it should count as a programming language, but they don't care anyway because they're busy throwing together things until it works. It also has a little brother for people without enough teef, which is basically the same except not.
