Agreed. With __update in place, there's no need for a 'proxy' table — we can use the real table directly, and reads can access fields from the real table without going through the proxy table's __index metamethod. 在2026年4月10日星期五 UTC+8 01:09:29<Martin Eden> 写道： On 2026-04-09 18:01, Rett Berg wrote: Currently we will create empty "proxy" table, store real table in closure, and use __newindex again. Ugly but works. With proposed __update we will use real table and use __update and __newindex. Code duplication but okay. If __update was proposed to replace __newindex then we will just use real table and __update.
