[Zope3-dev] _notifyOfCopyTo

[Florent Guillaume]

Zope 2, when it copies/moves an object, calls ob._notifyOfCopyTo to  
allow it to veto the copy *before* it is done if it doesn't like the  
destination container.

In Zope 3, is it worthwhile to have a kind of ObjectWillBeCopied/ 
Added event for that, or do you guys feel that this kind of vetoing  
should be done by simply subscribing to ObjectAddedEvent or one of  
its friends?

I'm asking because I'm in the middle of converting Zope 2's OFS  
spaghettis to cleaner event-based code (and deprecating things like  
_notifyOfCopyTo and _postCopy).
