Penny-wise, pound-foolish.  Saves 3 character strokes at the cost of a new
special-purpose operator which only works in limited circumstances.  To
avoid parsing ambiguity, identifier can only contain (as the name implies)
alphanumerics and _.  So your ! is limited not only to dicts but to certain
keys in certain dicts.  More complicated than it's worth.
