- peteforde 6mo agoI wasn't trying to be obtuse. Formal grammar / technical documentation style guides consistently define: [ ... ] = optional { ... } = repetition | = alternatives
- IshKebab 6mo agoHacker news isn't a formal grammar specification though. People use [1] for references here too (which you could easily have forgotten).
