aoqi@0:  *
aoqi@0:  * Self modifying assignments and ++/-- operators had two issues
aoqi@0:  * 1) the base was loaded twice
aoqi@0:  * 2) if the base was anything but an IdentNode, AccessNode or IndexNode and in the scope, it would
aoqi@0:  *    only be evaluated once, leading to bytecode stack underflow
aoqi@0:  *
aoqi@0:  * This file is split into two tests as the presence of eval affects the whole script
aoqi@0:  *
