    27  * Self modifying assignments and ++/-- operators had two issues

    28  * 1) the base was loaded twice

    29  * 2) if the base was anything but an IdentNode, AccessNode or IndexNode and in the scope, it would

    30  *    only be evaluated once, leading to bytecode stack underflow

    31  *

    32  * This file is split into two tests as the presence of eval affects the whole script

    33  *

    34  * @test

    35  * @run
