Because You can't otherwise guarantee to feed optional argument
parameters in a correct way.

Example:

x = property(*seq) where:
            seq = (item[1] for item in ::
                def get_x():
                    return self.__x
                def set_x(value):
                    self.__x = value
                del_x = None
                doc   = "I'm the 'x' property." )

This statement would not work if the result of '::' ( considered as an
"ordered dict" ) would return simply a dict because the order of the
input parameters matters.
