There's a problem with that code comment. I think it was originally destined for `VisibleMemberTable.allSuperinterfaces`, but somehow ended up on the wrong field. Thanks for noticing that.

As for more appropriate types: yes, we could use `Set`, but for that we would need to override `equals` and `hashCode` for `VisibleMemberTable`.
