Neither of which works in the case under discussion, where the access
type was declared inside a procedure and thus after the (global) type
definition.
I quite agree that Ada is a powerful language in which you can find
a way to do almost anything - but sometimes it takes a substantial
change in the design ( "make the pointer finalizable") to accomplish
the goal. It's usually also true that a new design is in fact much
better than the one that painted you into a corner. But in this case
it seems to me you are saying "do a big redesign, possibly affecting
any package that uses this type, in which a bunch of stuff is made
global and complex, instead of local and straightforward, or take the
risk of a major storage leak, or use unchecked programming". It might
even make a person include "no storage leak in this case" as a
criterion in choosing one compiler over another. You say it's
expensive to not have a storage leak in this case. Why? Do there
exist compilers that do leak? You've said Gnat doesn't leak - are
there plans to change that?
