Now we're straying into semantics. If the variable were `really' unset, as opposed to just appearing unset, that could be construed as meaning the global instance (or any previous local instances) would be gone, too. I could see pairing it with text that says the variable at the current or nearest previous instance is unset and remains so until that function returns.
