 - extended regression test
 
 - next-tutorial: documentation updates
+- add explicit reference counting for oacs-style flag value passing
 
+- parameter specs: use "arg=" in object parameter type "method" as
+  name of a called method to allow to call unregistered methods
+- eliminate protected method "noinit" for nx and allow it just as an
