----------------------+----------------------------

{{{
sage: ri=RealInterval(10,11)
sage: RealSet(ri)

in __classcall__(cls, *args)
634 intervals.extend(arg._intervals)
635 else:
--> 636 raise ValueError(str(arg) + ' does not determine
real interval')
637 intervals = RealSet.normalize(intervals)
638 return UniqueRepresentation.__classcall__(cls, intervals)
ValueError: 11.? does not determine real interval
