docs: Parameters
      ----------
      *dicts : iterable[dict]
          A sequence of dicts all sharing the same keys.
  
      Returns
      -------
      zipped : dict
          A dict whose keys are the union of all keys in *dicts, and whose values
          are tuples of length len(dicts) containing the result of looking up
          each key in each dict.
  
      Raises
      ------
      ValueError
          If dicts don't all have the same keys.
  
      Examples
      --------
      >>> result = dzip_exact({'a': 1, 'b': 2}, {'a': 3, 'b': 4})
      >>> result == {'a': (1, 3), 'b': (2, 4)}
      True
