Since the spec never says anything about protection on base 
classes/interfaces, and since it's been asked about many times, I guess it's 
one of two things: (1) a vestige from a long, long time ago when these were 
planned to work, but were never implemented, or (2) just there for future 
expansion.  It'd be interesting to see what code is there for it in the 
compiler frontend.
