Bug description: clarification: unset and reference
<%
function sub (&$v)
{
unset ($v);
$v = 66;
}
sub ($s);
echo '<br>$s = '. $s . "\n";
echo '<br>isset ($s) = '. isset ($s) . "\n";
%>
(a) unset breaks the reference between local $v
and parameter $s.
(b) $s becomes defined (no more warnings) by taking
a reference but it is not set.
Will this be documented?
