It kind of already does that if 'id' isn't set. But when 'id' is set, 
they diverge.

Also note that according to ILocation, __name__ is a TextLine, which 
implies unicode. unicode ids are a no-no in Zope 2.

The current solution I've put into dexterity is to let __name__ be a 
property that gets and sets id, but assumes its value is unicode. It'll 
fail if the unicode string can't be encoded to ASCII, though.
