dum-dum-non-tslisted

# Dum-dum non-TS Fires when writing or editing source files in non-TypeScript general-purpose programming languages: C, C++, Rust, Go, Python, Java, Kotlin, Swift, Ruby, PHP, Lua, Zig, Nim, Haskell, OCaml, Elixir, Clojure, Scala, F#, or any other. The skill encodes two rules (simplest possible constructs; comments on every concept-introducing line) and a comment template (What, Why, optional Gotcha) with a TypeScript pseudocode equivalent above every concept-introducing line. See "Out of scope" at the bottom for file types this skill does not apply to. ## Audience The human reader knows **only TypeScript**. Optimise comments and code shape for them, not for an experienced practitioner of the target language. The compiler does not read the comments; the user does. ## Two rules ### Rule 1 — Simplest possible constructs Write boring, beginner-level code. Forbidden by default: - macros, metaprogramming, reflection, code generation - operator overloading, custom conversion operators - template / generic gymnastics beyond a single type parameter - point-free chains, monad stacks, `do`-notation - decorators, mixins, multiple inheritance - comprehensions / generators when their syntax differs from TS - pattern matching used for control flow that an `if`/`else` chain handles - "clever" one-liners, ternaries longer than `cond ? a : b` Prefer: plain named functions, named local variables, explicit type annotations where
