OK, I kind of supposed you had something like that in mind. Many years
ago, we proposed a similar idea in a few papers, See for instance
http://www.adacore.com/wp-content/uploads/2006/03/Certification_OO_Ada_Answer.pdf.
Another one written by Franco G. is even mentioned in Chelinsky's FAA
study on OO (see http://www.tc.faa.gov/its/worldpac/techrpt/ar0717.pdf).
The study is worth reading by the way... We had more automatic
translation in mind at the time but the idea is the same.
