No need to recheck close method before calling it A to-be-closed variable is constant and it must have a close metamethod when it is created. A program has to go out of its way (e.g., by changing the variable's metamethod) to invalidate that check. So, it is not worth to test that again. If the program tampers with the metamethod, Lua will raise a regular error when attempting to call it.
