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.
