Yes, exactly.

Type casting combined with passing by reference is problematic in many
ways. Just an example:
fuction foo( string & $buffer) { ... }
foo( $my_buffer );
Here, $my_buffer has just been declared, so it is null. Should this be an
error? I don't know! So, I think that that passing by reference should not
be (immediately) supported.
