TL;DR – Proposing let? as a new syntax with zero‑runtime. An alternative to nested switches or Option.flatMap chains. It unwraps Ok/Some values and early‑returns on Error/None, and works seamlessly with async/await. Hi there! ReScript encourages explicit error handling with result and missing‑value handling with option, but real‑world code can quickly end up in one of two painful places: “Indentation chaos” - switches nested in switches to unwrap options and results Long map / flatMap chai...
