I like this idea. It accomplishes the goal of only using some of the keys
and has broader applications for working with dicts in general.
It might also be nice to have something that splits a dict into two, like
>>> items = dict(a=1, b=2, c=3)
>>> included, excluded = items &- {'a', 'b'}
>>> print(included)
{'a': 1, 'b': 2}
>>> print(excluded)
{'c': 3}
I don't know if I like the &- "operator" but it is illustrative.
