LuaJIT 3.0 proposed syntax extensions

LuaJIT 3.0 is proposing syntax extensions through an umbrella GitHub issue to consolidate and document language improvements. The proposed extensions aim to enhance developer experience while meeting criteria such as being proven in other languages, avoiding syntactic ambiguities, maintaining backward compatibility, and not complicating tool development. The maintainer emphasizes keeping discussions constructive and focused on functionality rather than subjective preferences about syntax symbols.
