In some cases, it would seem that not allowing exceptions to be thrown from destructors would be problematic rather than helpful. To leave destructors as a "blind spot" for detecting and reporting exceptions seems to be a very bad idea. I do not see why destructors are seen as poor stepchildren relative to all other contexts. This view will make for a basic inconsistency in the language. The rules must be more uniform or they will make a mess of it. You have to continue to destruct pieces in reverse order. Throwing an exception in a destructor is merely a special return from that piece of destruction analogous to the constructor case. To the contrare.
