-XXX explain that this is effectively type-specializing a loop
-
+If all the optimizations presented above are applied, the resulting
+optimized peeled loop will consist of a single integer addition
+only. That is it will become type-specialized to the types of the
+variables \lstinline{step} and \lstinline{y}, and the overhead of
+using boxed values is removed.
