There was a problem hiding this comment.
This could alternatively be elif, which would allow us to append anything to a SequenceValue (i.e., unannotated) list. But I just ran this branch internally and only got three errors, all of which were fixable by adding explicit annotations. I think such annotations are helpful, so I'll stick with this logic.
