[MacRuby-devel] Accessing objc methods aliased by ruby methods

For example, the method 'class' is present in objective C as well as in Ruby but invoking obj.class will use the Ruby version How do I force the objc version to be used instead? Obviously if the two version do the same thing then this is a moot issue but if they do different things you may need to choose the 'hidden' version. Thanks, Dave.
