Scott makes an excellent point. I just want to emphasise it by saying how useful that has been to me over the years - countless bugs killed at birth. I will admit it took me a while to get used to it, but the sooner you stop thinking about it the sooner it's natural. You may run into people who dislike it on religious grounds, however. For example, Google's internal style rules forbid it. Try to make sure you're paid by bug count, if you find yourself in that situation. ;) _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
