1.29 + *
1.30 + * Self modifying assignments and ++/-- operators had two issues
1.31 + * 1) the base was loaded twice
1.32 + * 2) if the base was anything but an IdentNode, AccessNode or IndexNode and in the scope, it would
1.33 + * only be evaluated once, leading to bytecode stack underflow
1.34 + *
1.35 + * This file is split into two tests as the presence of eval affects the whole script
