        # case, we will only (probably) be here if comment_key was a
        # ProgramComment key instead of a ProgramCommentReply key, so we would
        # probably want to have an error that's more specific (like TypeError
        # maybe?).  Man, there are so many edge cases with this stuff that I
        # really should look into now that I think about it...  We are also
        # probably going to need to keep a lot of this comment to explain why
        # we raise the error we do.
