In http://ruby-doc.org/core-1.8.7/Range.html it says:
Ranges can be constructed using objects of any type, as long as the objects can be compared using their <=> operator and they support the succ method to return the next object in sequence.


In http://ruby-doc.org/core-1.9.3/Range.html the above statement seems to have disappeared.  Has the semantics changed?
