Yes.
Having a getter property function return by ref does allow you to use a property exactly as you would a variable, because you're operating on the ref that's returned. It also makes the property function nigh-on-useless, because then you're operating on its associated variable outside of the property function, making it so that you can no longer control access to it. You pretty much might as well make it a public variable at that point. Not to mention, even if returning by ref didn't have that problem, it would only work in cases where the property function was associated with an actual variable (since you have to return a ref to _something_), so it would still be impossible to emulate a variable with property functions which calculate the value from other variables or which grab the value from somewhere else (e.g. a database). - Jonathan M Davis
