I suggest you read this recent thread for related commentary. http://www.serverphorums.com/read.php?7,712222 In there, I refer to your proposal as Contractual Call Super and I find it an interesting concept that helps avoid the "advisory call super" antipattern.

It means "cannot override." It doesn't mean "overrideable, but we'll call any/all supers before/after we run yours." It's a BC break. Fuggedaboutit. The feature you want isn't in the language -- maybe it should be -- and you can't change the meaning of existing keywords. -- S.
