pub fn close_slot(state: &mut LuaState, idx: i32) -> Result<(), LuaError>Expand description
C’s lua_closeslot: this clears the slot at idx (sets it to nil), but
does not invoke the value’s __close metamethod — a destructive but
incomplete stand-in. The host-side to-be-closed path is not wired into the
VM’s TBC machinery (issue #278); scripts still get full <close> semantics
via OP_TBC.
