Daniel,

    No, Range#end returns the object that defines the end of the range,
whether or not the range actually includes that object.  For
justification, think about how to handle "((0.0)...(1.0)).end".

>ri Range#end

-------------------------------------------------------------- Range#end
     rng.end    => obj
     rng.last   => obj
------------------------------------------------------------------------
     Returns the object that defines the end of _rng_.

        (1..10).end    #=> 10
        (1...10).end   #=> 10

    I hope this helps.
