I want to make a dictionary that acts like a class, in other words, supports inheritance: If you attempt to find a key that isn't present, it searches a "base" dictionary, which in turn searches its base, and so on.
Now, I realize its fairly trivial to code something like this using UserDict, but given that classes and modules already have this behavior, is there some built-in type that already does this? (This is for doing nested symbol tables and such.) --- Also, on a completely different subject: Has there been much discussion about extending the use of the 'is' keyword to do type comparisons a la C# (e.g. "if x is list:") ? -- Talin -- http://mail.python.org/mailman/listinfo/python-list
