This is a not-that important cleanup: It would be nice if we would tag or fix all methods with "sent but not implemented” selectors
if you inspect: SystemNavigation new allSentNotImplementedSelectors you get 160 methods in Pharo12. - some are dead code -> we should remove those - some are methods used for tests - there might be some that are send to objects with a DNU handler -> we should tag them using the < #ignoreNotImplementedSelectors: #()> Pragma - some are bugs -> we should fix those Helo is welcome! If we fix them all we can add a release test and make sure that code like this never is merged. Marcus
