+\subsubsection{Range Type \label{typesseq-range}}
+
+The range\indexii{range}{type} type is an immutable sequence which is
+commonly used for looping.  The advantage of the range type is that a
+range object will always take the same amount of memory, no matter the
+size of the range it represents.  There are no consistent performance

+Range objects behave like tuples, and offer a single method:

+  object.
