/*
* This test is completely analogous to oop_field_assignments.php
*
* For each of
*
* - object attribute assignment
* - (static) class attribute assignment
* - variable object attribute assignment
* - variable (static) class attribute assignment
*
* we test that
*
* - regular assignment works and that after a regular assignment,
* assigning to either variable does not affect the other
* - reference assignment works and that after a reference assignment,
* assinging to either variables *does* affect the other
* - reference assignment separates the RHS, if necessary
*
* for a total of 4 * 3 = 12 tests.
