> I created a derived class of the standard `dict' that fills in a default> value when a key is not found. This is exactly the same as Guido describes> in his "descintro" paper. I tried to use this dictionary as the "globals"> parameter with eval(). As Guido already describes in his paper, this doesn't> work.I've wanted this for years and think it would be an importantimprovement.
