+=head2 keep_stash
+
+You can choose to not localize the stash for SubRequests' subinclude calls. The subrequest
+will have the same stash as the request that spawned it. Configure the keep_stash key
+in your view:
+
+    __PACKAGE__->config(
+        subinclude => {
+            'SubRequest' => {
+                keep_stash => 1,
+            },
+        }
+    );
+
+Note: the stash that the subrequest recieves is a shallow copy of the original stash. That
+means that changes to values of keys on the first level of the stash will be lost when the
+subrequest call returns. Don't count on this behaviour, as it may change in the future.
