Yeah, but I have lots of potential attributes, and lots
of inheritance relationships - which makes the method signature
unwieldy - just what **kw seems to be made for.

Looks like I'll end up with building a list of attributes and something
like:

for key in kws:
   if key not in optlist:
      print 'WARNING  " %s" not a valid keyword for %s'
%(key,self.__class__.__name__)

Just found a bunch of typos in my demos doing this approach.
