I'm not sure I understand what you mean. Are you saying it's bad to do the *first* assignment to a variable inside a conditional? Or it's bad to assign inside a conditional in any case? I can understand the first, but I'm not sure how you would work around the second, unless you used a more functional style like x = (n > 2 ? true : false) or x = (if n > 2; true; else false; end) _______________________________________________ MacRuby-devel mailing list MacRuby-devel@lists.macosforge.org http://lists.macosforge.org/mailman/listinfo.cgi/macruby-devel
