Pro: * -[NSObject init] is in fact guaranteed to do nothing. Con: * As you noticed, independent of its correctness, the code above *looks* wrong. That alone is bad. It ought either to call -init or to have a big scary comment describing why it is safe not to. * If Foo is ever changed to have a superclass other than NSObject, the code above is likely to be wrong. -- Greg Parker gpar...@apple.com <mailto:gpar...@apple.com> Runtime Wrangler _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
