Ugh, wish I’d have thunk of this one
Create a Brobdingnagian monstrosity of 1.2m lines of Haskell. That way, the tooling you create to make working on it tolerable will be practically instant on codebases that don’t need 18 lanes for a 3 point turn. (With love and appreciation, @mercury)
“Semigroup” and “Monoid” are exclusionary terminology. Prefer “smashy-smashy” and “smashy-smashy-with-extra-nothing”.
Tired of probabilistic correctness guarantees? instance Arbitrary UUID where … shrink uuid = case UUID.toWords uuid of (a,b,c,d) -> [UUID.fromWords a' b' c' d' | a' <- sw a, b' <- sw b, c' <- sw c, d' <- sw d] where sw w = take 10 $ iterate (`div` 2) w

Performance tip: s/sequence/mapConcurrently/g Good code can be run in any order.
The great thing about using Haskell with LLMs is that you can be absolutely precise about the nonsense you are ingesting and emitting.
If you're writing a parser for some type t, one fun thing to omit is a way to turn it back into a string. Easy visualisation, canonicalisation and roundtrip properties are for people who insist on putting bugs in their code and there is no reason to coddle them.
