> At the moment, some checked arithmetic operators (CHECKED_PLUS, CHECKED_MINUS, CHECKED_TIMES, CHECKED_MINUS_PREFIX) are part of the {{safeOps}} set in {{RexSimplify#SafeRexVisitor}}, i.e. they are considered "safe" by {{RexSimplify#isSafeExpression}} .
> To be reviewed if these operations should be considered actually "safe", since they can throw at runtime (in case of overflow), similarly to e.g. a division by zero, which is considered "unsafe".
