Feedback?

I would like this to be part of the standard dictionary type, rather than being a subtype.

d.setdefault([]) (one argument) should install a default value, and d.cleardefault() should remove that setting; d.default should be read-only. Alternatively, d.default could be assignable and del-able.

Also, I think has_key/in should return True if there is a default.

Regards, Martin
