Hi, I noticed that recent LuaMetaTeX versions treats control sequences defined using token.set_lua with `value` or `condition` as frozen and does not allow redefining them. Given that these are not macros, we also can't "unfreeze" them using \unletfrozen. 1. Would it be possible to add a variant of Lua value and condition control sequences that are not frozen? 2. Also is there some way to disable the \frozen restrictions altogether? Maybe \suppressfrozenerror? 3. I also noticed that `token.set_lua` is not affected by control sequences being frozen. Therefore it allows redefining frozen control sequences which seems inconsistent. Best regards, Marcel
