First, I think this should be fixed in Ada0Y.  Not necessarily full 
garbage collection, but...

Ada95 has a requirement that Unbounded_Strings not leak storage.  This 
can be done by reference counting or whatever, but it has to be there. 
I have a nice little package that uses Unchecked_Conversion to put 
arbitrary objects in Strings.  Obiously pointers "hidden" this way will 
break the abstraction.  But I find it is a very useful language extension.

Second, and this is again something that puts no burden on compiler 
vendors, there should be a standard generic garbage collection package 
which uses a named storage pool.  Write it, propose it, and Ada0Y will 
have a standard Ada.Garbage_Collection package.
