This is the situation. I've got another container which holds
instances of WebSearch. I've used both the dict option and the
setattr technique. Both work nicely. In writing the example I posted
I began to wonder about the other question.

Thanks for all your help.

I was going in the right direction, and now I have a better idea of
the pythonic way of solving things.

Again, thanks.
