So, the problem I'm seeing is what I alluded to earlier: writing stuff in the class body is more like +load than +initialize. Especially, not all classes may be loaded at that point.

So I came up with this: http://gist.github.com/619585

Would it make sense to try to have something official for this functionality?


In the process I noticed a few things:

1. You may see I opted for using _initialize instead of initialize for the method name. It turns out every ruby class in MacRuby already respond_to?(:initialize). That's not true in MRI. Is this a necessity of the Objective-C implementation?

2. It appears that the #singleton_class method does not exist in MacRuby. Oversight? File a ticket?

3. I initially tried implementing Object.inherited as:

    class Object
      @inherited = []
      def self.inherited(m)
        @inherited << m
      end
    end

This works in a standalone MacRuby file. In the context of an application, @inherited seems to be lost, and I get an error trying to call << on nil. What's going on here?
