+Inference of Dependent Types in Generic Instantiations
+------------------------------------------------------
+
+If a generic formal type T2 depends on another formal type T1,
+the actual for T1 can be inferred from the actual for T2.
+That is, you can give the actual for T2, and leave out the one
+for T1.
+
+For example, ``Ada.Unchecked_Deallocation`` has two generic formals:
+
+.. code-block:: ada
+
+    generic
+       type Object (<>) is limited private;
+       type Name is access Object;
+    procedure Ada.Unchecked_Deallocation (X : in out Name);
+
+where ``Name`` depends on ``Object``. With this language extension,
+you can leave out the actual for ``Object``, as in:
+
+.. code-block:: ada
+
+    type Integer_Access is access all Integer;
+
+    procedure Free is new Unchecked_Deallocation (Name => Integer_Access);
+
+The compiler will infer that the actual type for ``Object`` is ``Integer``.
+Note that named notation is always required when using inference.
+
+The following inferences are allowed:
+
+- For a formal access type, the designated type can be inferred.
+
+- For a formal array type, the index type(s) and the component
+  type can be inferred.
+
+- For a formal type with discriminats, the type(s) of the discriminants
+  can be inferred.
+
+Example for arrays:
+
+.. code-block:: ada
+
+    generic
+        type Element_Type is private;
+        type Index_Type is (<>);
+        type Array_Type is array (Index_Type range <>) of Element_Type;
+    package Array_Operations is
+        ...
+    end Array_Operations;
+
+    ...
+
+    type Int_Array is array (Positive range <>) of Integer;
+
+    package Int_Array_Operations is new Array_Operations (Array_Type => Int_Array);
+
+The index and component types of ``Array_Type`` are inferred from
+``Int_Array``, so that the above instantiation is equivalent to
+the following standard-Ada instantiation:
+
+.. code-block:: ada
+
+    package Int_Array_Operations is new Array_Operations
+      (Element_Type => Integer,
+       Index_Type   => Positive,
+       Array_Type   => Int_Array);
