Hi netters, I've written some applications on NeXT, using Objective-C. It works fine and I like Objective-C so far. I have two questions which I couldn't find their answer on NeXT's documentation. First question: How can I declare statically-typed, mutually-referenced objects? Are there any mechanism analogous to C++'s "extern class A"? Second question: Does static declaration of objects improve the speed of method selection? If not, messaging like [foo display] should be equivalent to [foo perform: @selector(display)] since ObjC performs dynamic method selection in both cases; am I right? If these are sort of FAQ, could someone point out where this newsgroup is archived and how can I get it. Thanks in advance, -- Youki Kadobayashi Dept. of Info. and Comp. Sci, Osaka University, Japan
