In the example you've given you've deprecated only keyword arguments. So I was wondering...

would the following *untested* code work ? :

def check_deprecated_args(deprecated):
  def decorator(func):
    def inner(*args, **kwargs):
      for p in deprecated:
        if p in kwargs:
          print '%s is deprecated' % p
      return func(*args, **kwargs)
    return inner
  return decorator
