+C# / .Net
+^^^^^^^^^
+
+.Net has a generic ``Dictionary`` class where you can specify a custom
+``IEqualityComparer``: http://msdn.microsoft.com/en-us/library/xfhwa508.aspx
+
+Using it is the recommended way to write case-insensitive dictionaries:

+
+Java
+^^^^
+
+Java has a specialized ``CaseInsensitiveMap``:
+http://commons.apache.org/proper/commons-collections/apidocs/org/apache/commons/collections4/map/CaseInsensitiveMap.html
+
+It also has a separate ``IdentityHashMap``:
+http://docs.oracle.com/javase/6/docs/api/java/util/IdentityHashMap.html
+
+C++
+^^^
+
+The C++ Standard Template Library features an ``unordered_map``
+with customizable hash and equality functions:
