Until .id is removed from the vocabulary (and probably a long while 
afterwards so that people can assume backwards compatibility), it 
shouldn't be overridden.

I'm not really looking for a workaround. Either I use the workaround 
every time I need to get the name of a class, or we get this one 
instance fixed. I don't find that very acceptable, so for now I have to 
deal with the possibility of a nil name and just fake it.
