This is intentional behaviour, there are times when you want a copy of a
reference and there are times when you want a reference to a reference.
For instance consider the following:
$foo1 = $foo2 = $foo3 = new a();
$foo2 = new b();
If these were references to references instead of copies of references
then $foo1, $foo2, and $foo3 would all now refer to the newly created b
object.
Cheers,

OK I'm pretty clear on it, but now I wonder: is variable assignment (=)
the only place where the Zend Engine will copy a reference instead of
reference the reference?
