I see. You want to show arrays as your revealing data.

 (a) If you don't need full set of Array API, provide alternative API,
     for example:

     class X
        ...
        def [](n)
        end
        def []=(n,val)
        end
     end

 (b) return Array-like object, that updates internal CStruct when it's
     modified.  MetaRuby would help you.  See RAA for more information
     about MetaRuby.
