I don't think the attr_accessor is relevant. What's happening is this:

'private' with no arguments makes all following methods private. The  
getHash method is private. When you call it from outside the class,  
ruby fails to find the method and invokes method_missing if defined.  
If it wasn't, you'd get something like:

   private method `getHash' called for #<Y:0x4fce88> (NoMethodError)

Since method_missing is defined by RubyCocoa, it does the method  
lookup, which ignores the method protection.

Solution: add 'public' sometime after 'private' in order to reset the  
protection.


Hope that makes sense.
