I would say that this last criterion is clearly impossible. Large sections
of the front end assume intimate familiar with the Ada RM, and understanding
patches for the front end must almost always assume a pretty deep level of
Ada knowledge. However, I am not clear that ZW was making this request.
It would make no sense, so I really did not assume that this was the
intent. For example, any of the patches for implementing Ada 2005
features assumes complete familiarity with the (often very complex)
corresponding AI, and the AI itself generally assumes complete
familiarity with the RM.
