 This doesn't reduce the total complexity, but it reduces the surface complexity presented to many users.
 To really reduce the number of arguments, we need to bundle the arguments into higher-level abstractions:
 
-	template<class InputRange2, class InputRange2, class OutputIterator>
+	template<class InputRange1, class InputRange2, class OutputIterator>
 	OutputIterator merge(InputRange1 r1, InputRange2 r2, OutputIterator result);
 
 Grouping arguments into "bundles" is a general technique to reduce the number of arguments and to increase the opportunities for checking.
