Every time I have encountered an unexpected list it has been because of
a bug somewhere else in my code. I might use a getone() method that
threw some exception when a list was encountered, but I'd *never* want
to use getfirst(). getfirst() is sloppy programming. (getlist() is
perfectly fine though)
