Could you make a conclusion on the topics below?
1) Legal type pairs that is assignable in validation but illegal in runtime.
2) Apart from Union, other SetOps (e.g., Intersect) have the same problem?
3) According to the context and discussion in [CALCITE-3565](https://issues.apache.org/jira/browse/CALCITE-3565) and [CALCITE-3414](https://issues.apache.org/jira/browse/CALCITE-3414), can we use `EnumUtils.convert`?
