I'm not 100% sure I agree with this refactoring since like I mentioned in a prior comment it was the intention of the Expression enum to express nested expressions which should come up from nested dereferences/array accesses like ****foo or bar[0][0][0]. I think the fact that we don't ever use the recursiveness of the enum to be indicative of bugs we likely have handling aliases of these nested cases.
That being said, it is true that this better represents the code as we have it now and it's not too much more effort to re-add in the future (maybe during this same audit) if we get such a bug whose fix involves properly using this enum as intended. If that doesn't happen though, it'd be simpler for external auditors not to worry about this unhandled case.
