what is the idiom for copy lots of params into self?

[Emin]

Dear Luis and everyone else who responded,

Thanks for your suggestions. One issue with using *args or **kw is that
I might no want to copy all the arguments to __init__ into self.

What made me ask the question in my original post was not so much that
I had to loop over the names I wanted to save, but whether it's okay to
mess with self.__dict__ or if there is another way I should be
assigning to self.

Thanks,
-Emin
