Where do you propose to get these names from? Lists and
dictionaries don't have names...

I agree with the general idea of providing some sort of
identifying information, but in these cases I can't think
what sort of information would be useful short of displaying
the entire repr() of the object, which would be too much for
a backtrace message, I think.
