Except that that's two statements and it's no longer RAII. The beauty of doing
it entirely in the constructor and destructor is that you only need one
statement and the whole thing takes care of itself. With scope, you have to
worry about remembering to use scope, and even if you do, that's two statements
instead of one. Obviously, it works, but it's not as clean or elegant.
