Stef,
Which is more important:
implementation or functionality?
functionality: how to store meta data of class or method. So far I do not see why I need ston. Now if you tell me that you need a textual serializer then this is another story and scenario. But this is not the one we need to store meta data of class and method. I'm not that approximate to mix the two. Stef
You appear to be fixated on a particular solution and seem to be ignoring the actual problems.
