But it is. All of the objects allocated from an access type are logically 
deallocated when the access type goes out of scope (and the memory can be 
recovered). Remember that Ada was designed so that one never needs to use 
Unchecked_Deallocation.

I could see an unsafe language (like C) doing the sort of thing you suggest, 
but not Ada. Every object in Ada has a specific declaration point, 
initialization point, finalization point, and destruction point. There are 
no exceptions.
