Umm.  As an afterthought to my previous message, I guess it goes without
saying that this is a clear design/programming error in a type-safe
program, and that what *should* have happened is to have <flightless> and
<flightfull> subclasses of <bird> AND/OR have a <flying-thing> mixin
class.

In a program not intended to be fully type-safe, it's OK just hwo it is
:-)  It would be nice if we could support both styles.
