Me too.  I think it's one of those mistakes that sticks in the mind.

It might make tracing elaboration errors easier.  :)

Barnes says "... in any handler we are assured that all declarations of 
the unit were successfully elaborated and so there's no risk of 
referring to something that does not exist."  That's sensible but it 
does mean the compiler has to undo memory allocations if they occur in a 
declaration and a subsequent declaration raises an exception.
