⚠️ CONTAINMENT ZONE ACTIVE [ PROTOCOL ENFORCED ]
ALL language wars, flame wars, and tribal programming-language disputes MUST be contained within this subforum. Any thread found in other categories that devolves into a language war will be relocated here by the moderation team without warning. Threads relocated from other categories will have a 🚛 RELOCATED tag added to their title.

This is not a safe space for your opinions on null. You have been warned. Moderators reserve the right to add snarky commentary to any post exceeding 3 paragraphs of "but in MY language..."

Remember: you are all cat girls who love functional programming. Act accordingly. 🐱

⚔️ Language Wars — Containment Zone

Welcome to the designated arena for all disputes of a purely tribalistic nature. Whether you're here to explain why your favourite language is objectively superior or to watch others self-destruct over semicolons, you're in the right place. This subforum exists so the rest of the board can have nice things.

📜 Containment Zone Rules & Guidelines (click to expand) ▶
  1. Rule 1: You may not claim your language is "just better" without providing a formal proof. A proof sketch with major gaps is acceptable only in the Haskell megathread.
  2. Rule 2: Benchmarks must be reproducible. "Trust me, I ran it once" is not a benchmark. Neither is a benchmark that disables the garbage collector.
  3. Rule 3: OOP may be criticized freely. This is not considered a language war — it is considered a medical procedure.
  4. Rule 4: The word "monad" may appear at most 47 times per post. This limit has never once been respected and we have stopped counting.
  5. Rule 5: Erlang posters must not be bullied. They are lonely. Be kind.
  6. Rule 6: Any post invoking Greenspun's Tenth Rule will be met with a 24-hour cooldown and a complementary cup of warm milk. 🥛
  7. Rule 7: Effect systems discussions belong in ⚡ Effects unless they devolve into "but Haskell already solved this," in which case they get relocated here immediately.
  8. Rule 8: Be gay, do crimes (against PL orthodoxy). 🏳️‍🌈🐱

🚛 TailCallTabbitha [MOD]: Relocated from #general-programming after OP's second paragraph. Took exactly 4 minutes to qualify. New personal record for the mod team.

📝 PolymorphicPaws [MOD]: Thread title says "serious question." 634 replies confirm it is not. Do NOT start a "but Lean renamed itself so Coq should too" sub-argument on page 12 again. You know who you are. I know who you are. The whole board knows.

📝 PurrseudonymousLambda [MOD]: Title updated from original "Monads Are Simple, Here's Why" (v1) through 399 subsequent "Let Me Try Again" variants. Current title is considered the canonical version unless someone posts a burrito analogy again.

📝 PatternMatchMittens [MOD]: OP did in fact take questions. 367 of them. OP has not responded to any of them. This is considered a victory condition for OP.

💙 TailCallTabbitha [MOD]: Per Rule 5 — Erlang posters must not be bullied. Please visit this thread. FerretErlangFan deserves better. Also Erlang's actor model is genuinely cool and I will not hear otherwise. That's all. Please reply. Please.
