  26  *
  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
