+1. I often use this idiom. You can do it going forwards, but it introduces an if/else that makes the code sort of confusing (and easy to mess up.) It's also more efficient than removing the elements in forwards order (proof of this is left as an exercise for the reader.) —Jens_______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
