trace options

I need a dict that inherits its mappings

I need a dict-like object that, if it doesn't contain a key, will return the value from a "parent" object. Is there an easy way to do this so I don't have to define __getitem__ and __contains__ and others that I haven't even thought of yet? Here's a use case, if you're confused: en_GB=mydict() e
