Again, assignment works differently here:

$v = NULL;
$v->foo->bar = 42;
// Warning: Creating default object from empty value

Interestingly, only one Warning is issued for this case, even though the 
inner value must also be created. This seems like a more useful 
behaviour, because it doesn't clutter the log/output with repeated 
notices about a single line.
