/**

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