+Type casting
+------------

+The "as" operator performs type casting and the "is" operator checks if a
+type cast is supported or not.  For both operators, the first operand is a
+value and the second operand is the name of a Bro script type (either built-in
+or user-defined).

+
+Only the following kinds of type casts are supported currently:
+
+- Broker values (i.e., values returned from functions such as
+  :bro:id:`Broker::data`) can be casted to their corresponding Bro script
+  types.
+- A value of declared type "any" can be casted to its actual underlying type.
+- All values can be casted to their declared types (i.e., this is a no-op).
+
+The function in this example tries to cast a value to a string::
+
+    function example(a: any)
+        {
+        local s: string;
+
+        if ( a is string )
+            s = (a as string);
+
+        }

+    There is an alternative form of the switch statement that supports
+    switching by type rather than value.  This form of the switch statement
+    uses type-based versions of "case":
+
+    - "case type t: ...": Take branch if the value of the switch expression
+      could be casted to type t (where "t" is the name of a Bro script type,
+      either built-in or user-defined).
+
+    - "case type t as x: ...": Same as above, but the casted value is
+      available through ID "x".
+
+    Multiple types can be listed per branch, separated by commas (the "type"
+    keyword must be repeated for each type in the list).
+
+    Example::
+
+        function example(v: any)
+            {
+            switch (v) {

+            }
+            }
+
+    Note that a single switch statement switches either by type or by value,
+    but not both.
+
+    Also note that the type-based switch statement will trigger a runtime
+    error if any cast in any "case" is an unsupported cast (see the
+    documentation of the type casting operator "as").
