This proposal originally arose out of a workshop organized by Ada-Europe. It was quite complex and considered far too radical a change and probably expensive to implement. As a consequence it was slimmed down considerably. But having been slimmed down it seemed pointless and was then abandoned. The only part to survive was the idea of raise with message which became a separate AI and was incorporated into Ada 2005.

This was not pursued in Ada 2012.
