However, if such a class has static member functions, then simply writing `LOG()` will not work because name lookup will find the non-static member function and no the global function, resulting in a compiler error because the non-static member cannot be invoked without an object, and there is no object in a static member function. This can be avoided by using `using libcamera::_log;`, thereby bringing the global declaration into the current scope.
