Failure to understand the evaluation order of expressions containing side effects can result in unexpected output.
Rule | Severity | Likelihood | Remediation Cost | Priority | Level |
|---|---|---|---|---|---|
EXP05-J | Low | Unlikely | Medium | P2 | L3 |
Automated Detection
Detection of all expressions involving both side effects and multiple operator precedence levels is straightforward. Determining the correctness of such uses is infeasible in the general case; heuristic warnings could be useful.
