Attempts to retrieve the input value's metatable, and returns it if found. If the value does not have a metatable, returns {nil}. If the input value does have a metatable, but that metatable is not possible to retrieve because it is protected with the `__metatable` metamethod, returns {false}.

This is a useful way to ensure that functions can reliably distinguish between objects that do not have metamethods, objects with known metamethods, and objects with unknown metamethods.]==]
