<br>
</span>I think we'd be much better off having a list of all cases. That would make this feature useful for enums which don't have a raw type, or don't use Int as their raw type, or don't use sequential raw values for their cases.<br>
<br>
That approach has been discussed before, but not formally proposed.<br>
