You, my friend, are a sick man! But then again, I already knew that ;-)

I wouldn't propose the latter seriously as an enhancement to the dict object:
imagine all the c.l.py posts we'll get of people who do

  >>> d = {}
  >>> d.keys = <whatever>

and wonder why it blows up later... What Oren posted is a great hack in cases
where you more or less know the kind of keys you're going to expect, but it
isn't as great as a general feature of dicts.
