  def u(**kwargs):
    return tuple(kwargs.values())
Am I missing something, is this effectively the same?

*I realize the tuple can be omitted here

Or use itemgetter:

  >>> from operator import itemgetter
  >>> dct = {'greeting': 'hello', 'thing': 'world', 'farewell': 'bye'}
  >>> thing, greeting = itemgetter("thing", "greeting")(dct)
  >>> thing
  'world'
  >>> greeting
  'hello'

There are so many things like this one in the standard library that it kinda pisses me off when I discover a new one.

Ohhh, nice. Also, attrgetter (which also supports dotted notation to get nested attrs! Sadly, no dotted notation for itemgetter.)
