Right. I was thinking about that at some point, too.

I agree with the classes you mention, but we also need a SyntaxError or
similar kind of thing for malformed structures: the program expects some
ZZ structure, but gets something else. This should probably be an error,
because it usually needs to be handled by the user somehow, not the
calling function.
