Yes, at this time.  Specifically, you should only raises [instances of] 
subclasses of the builtin class Exception, which is itself a classic class
as of 2.2 (and 2.3, at least judging from what's in CVS now).  This is
not (yet?) strictly enforced, but the fact that the class of what you
raise must be of the same object-model as Exception (which, currently,
means classic) IS.
