Debugging
Liminal
Expert analysis and derivation for delimited continuations and defunctionalization, using CPS, shift/reset, prompt/control, abstract machines, effect handlers, and continuation runtime strategy as supporting lenses. Use when Codex needs to compare control operators, explain a witness program, derive CPS or abstract machines, first-orderize higher-order semantics, plan continuation implementations or benchmarks, explain typed control tradeoffs, or build source-backed study and research roadmaps across Racket, OCaml, Haskell, Scala, JavaScript, or language-agnostic settings.
