<div dir="ltr">With the SystemChangeNotifier (events), you can get notified que a method was added, changed, removed, etc., but you can not stop adding/changing or removing a method from happening. That is the difference I see with what you propose.<div>We could "enhance" the system change notifier to add that functionality, and I think that would be better because it is more consisten with what the system does right now and it would not be coupled with a class hierarchy and no redefinition of methods would be necessary.</div><div><br></div><div>If you ask me, I would enhance the system change notifier</div><div><br></div><div>Hernan.</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Jan 23, 2020 at 6:56 PM Phil B <<a href="mailto:pbpublist@gmail.com">pbpublist@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="ltr">A correction / clarification...</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Jan 23, 2020 at 4:35 PM Phil B <<a href="mailto:pbpublist@gmail.com" target="_blank">pbpublist@gmail.com</a>> wrote:</div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_quote"><div>I think this functionality is interesting, I would add it making the change of #compile:...
