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

And exactly what use would it then be ?

Code that checks

if d.has_key(k): print d[k]

would work correctly. IOW, you could use a dictionary with a default key just as if it were a normal dictionary - which is a useful property, IMO.
