There's another proposal in the pipeline, regarding the addition of
extra info to various exceptions, and one of the points it makes is
that suggestions could be made on NameError (which would probably be a
feature wanted more in interactive mode than elsewhere). How easily it
can be made truly useful is anyone's guess; I generally find that "Did
you mean" lists are more often useless than helpful.
