+Local goto labels
+=================
+
+This can be used to provide scope for goto labels and avoid accidentally
+jumping to an unrelated block.
+
+Syntax idea (borrowed from the GCC extension):
+
+    func f()
+    {
+        {
+            label skip
+            ...
+            goto skip
+            ...
+          skip:
+            ...
+        }
+        {
+            label skip
+            ...
+            goto skip
+            ...
+          skip:
+            ...
+        }
+    }
